Se le llama glucemia a la glucosa que está en la sangre, tiene que encontrarse 5mm en la sangre para que un paciente este normal. La insulina es una hormona que se secreta en el páncreas exactamente en los islotes de Langerhans por su factor beta, esto ocurre cuando a través del Glut 2 membranal los detectores de glucosa encuentran una concentración más alta a lo necesario

Esta hormona (la insulina) viaja por el torrente sanguíneo y afecta las células hepáticas, neuronales y musculares para que capten glucosa. La insulina se une al receptor membranal de insulina

Si la concentración de glucemia es baja los RTK activan la vía PI-3 cinasa. Al final de esta vía de señalización se activa la proteincinasa B PKB que activa las vesículas de GLUT4 que se desplazan y se fusionan con la membrana para hacer que la glucosa entre en la célula. Tras eliminarse la insulina los GLUT4 sufren endocitosis y comienza la producción del glucógeno. Esto hace que se reduzca la degradación de glucosa a piruvato y este efecto es el opuesto al de la hormona glucagón que se produce en el páncreas.

Existen diversos tipos de GLUT que son los receptores de glucosa en las membranas celulares, algunos ocupan ser activados mientras otros no. Por lo cual el cerebro logra captar la glucosa sin la necesidad de utilizar la insulina al usar el Glut 3

Cuando existe una falla en el metabolismo de la glucosa y la insulina se obtiene niveles altos de glucemia que deben de ser controladas con dietas muy estrictas. Esta enfermedad se conoce como “Diabetes” que existen 2 tipos: El tipo 1 es en el que las células beta casi no producen insulina, y el tipo 2 es el que la captación de la glucosa por las células y sus receptores se ve afectada y no se produce suficiente insulina.

Responsibility Towards Natural Resources

...Personal Responsibility Toward Natural Resources Nature is represented by all the living and non-living organisms on this planet. Water, plants, mammals, fish, mountains, all have a role in the ecosystem, and are dependent on one another. Although the most dominant species, humans are also the most dependent of them all. We, humans, depend on nature and its resources to survive; yet it seems that we are unaware of this fact, judging by the way we waste and abuse our natural resources. Our quality of life is directly related to natural resources and using them responsibly would ensure that the next generations will also have those resources available. That is not the case however, not only have we almost depleted the supplies of coal, oil, and natural gas, but we processed them negligently, so our waters, atmosphere, and land are polluted as a result of it. Earth has no rights, unlike us, humans, that are protected by the constitution of the country we reside in. How will Earth defend itself from the species that has the most judgment on the planet and it still ignores the signs that the planet is sending us: ozone layer is thinning, global warming, ice caps are melting, fish dying in the rivers and oceans due to contamination, extinction rates skyrocketing due to deforestation and urbanization. The impact of hundreds of species being extinct and hundreds other considered endangered is also mentioned in Reading Literature and Writing Argument “research shows that preserving...

Euthanasia

...euthanasia morally justifiable? What is euthanasia? According to J. Gay-Williams euthanasia is taking a human life, either one’s own or that of another, the life being taken is believed to be suffering from some disease or injury from which recovery cannot reasonably be expected. These actions must be deliberate and intentional. J. Gay-Williams believes that euthanasia is not morally justifiable. Williams gives three main reasons to justify why he believes that euthanasia is not morally justifiable. He argues that euthanasia is not natural, works against self-interest, and it has practical effects. He believes that euthanasia is not natural. he also explains passive euthanasia which he believes is not euthanasia. Passive euthanasia is not giving someone their needed medicine or not giving someone their needed medicine. He feels that euthanasia is unnatural because it goes against our natural goal of survival. He feels that by ending a life that we do not know what will happen in the end is against God. Williams also says that euthanasia sets us against our own dignity. It takes away our dignity because instead of fighting we are giving up and seeking an end to the battle. Williams feels that euthanasia works against our self- interest. He feels that death is the end and allowing euthanasia to be practiced goes against our self- interest. Using euthanasia as an outlet from life can be wrong because people are wrongly diagnosed daily and someone could believe they are not going...

Ecology

...last 50 years or so has led to a rapid increase in the rate at which the world population is growing. In future, world population is expected to reach a growth peak and there will be a drop due to different factors such as environmental hazards, economic reasons, land exhaustion and health concerns (Neal, 2004). The number of births and deaths usually determines population change. If the number of births exceeds the number of deaths then population growth is said to have occurred. The factors that are known to affect population growth include fertility rates, family size (small families are more common in developed countries, larger in developing countries), and mortality rates determined by access to medical facilities, accidents, natural disasters. The world population is estimated to be growing at a rate of 180 new persons per minute or 43 million new births per year. Demographic transition in less developed countries in recent times has been marked by gradually declining birth rates preceded by an earlier reduction in death rates. Demographic transition is the transition between high birth and death rates to low birth and death rates (Neal, 2004)....

Stop All The Clocks Metaphors

...stanza, the speaker uses the muffling of sounds as a metaphor for his wish for detachment from reality after his lover’s death. In the fourth stanza, the speaker’s illogical demands to disrupt the natural phenomena reveals that the death of his lover devastated him and that the world is no longer meaningful to him. The metaphorical commands in these stanzas reveal that the world after the death of the speaker's loved one is forlorn, dark, and absurd to him. The figurative language in the first stanza indicates that the death of the speaker’s loved one causes him to wish to become detached...

Comparative Analysis of Robert Frost

...Prizes, and even reciting one of his poems at President John F. Kennedy’s inauguration. Frost was born in San Francisco, but spent most of his life in New England, as a teacher and farmer, in rural New Hampshire. Frost often uses natural elements in his poetry, especially New England landscapes. He uses seasons, flowers, fields, stars, and time of day to set a logical sequence of events to paint a psychological feeling inside the reader’s mind. Two of Robert Frost’s poems, “Desert Places” and “Stopping by Woods on a Snowy Evening”, take readers through a New England winter setting, reflecting the beautiful scenery through his descriptive imagery. However, even though these two poems are set in a wintry backdrop, they convey very different tones. One has a feeling of loneliness, and the other a welcoming feeling of solitude. In this paper, I intend to illustrate how two very similar natural settings are written to express two very different themes of loneliness. The poems “Desert Places” and “Stopping by Woods on a Snowy Evening” have quite a few similarities. For instance, they both share the same rhythmic scheme; A,A,B,A. They both are set in a snowy, evening where darkness is taking over quickly. In both poems there is a man traveling alone, where no other souls are around. There is a sense that both travelers are stepping away from life for a brief moment in time. The contrast of darkness and whiteness against the horizon is apparent in both poems, however in “Stopping by...

STEVEN POMARICO Outline 1A CHAPTER 1 AN INTRODUCTION TO LIFE ON EARTH What is Biology? --- The science of living organisms and life processes. O.K., so what is science? And If biology is the science of “life,” what exactly is life? We all recognize what life is, but it’s difficult to define. The characteristics of life: 1) -Complex, organized structure 2) -Response to stimuli - a change outside (or inside) leads to another change 3) -Homeostasis - the ability to maintain the structure and regulate the internal environment. 4) -Ability to acquire material and energy >The material and energy are often transformed< 5) -Growth 6) -Reproduction - either sexual or asexual >DNA is genetic information, the “blueprint” for the offspring< 7) -Ability to evolve - to change to fit the environment Complex, organized structure The complexity of life is built in levels. (see fig 1-2) Each level has ingredients or components which interact to make something greater than the sum of the parts. -Subatomic particles -Atoms -Molecules -Organelles (not present in prokaryotes) -Cells -Tissues (present only in multicellular eukaryotes) -Organs (present only in multicellular eukaryotes) -Organ systems (present only in multicellular eukaryotes) -Multicelled organisms -Populations -Community -Ecosystem -Biosphere Response to...

Palliative Care Patients

...At the end of life, patients and their families are faced with many difficult choices. One of these choices is deciding whether to withdraw or continue enteral feedings that their loved one has been receiving. Some researchers argue that withdrawing enteral nutrition at the end of life allows the natural dying process to occur and increases comfort because patients are not administered feedings that the body can no longer absorb. Other researchers argue that providing nourishment during palliative care enhances the course of treatment and can improve patient outcomes. The goal of this paper is to demonstrate in palliative care patients, what is the effect of withdrawing enteral nutrition compared to continuing enteral nutrition on quality of...

Physcian Assisted Death

...people like to avoid the discussion, hence the number of people that don’t preplan their funeral and death plans. Regardless of whether we want to plan or not death is always 100% sure when its time. No human being has lived forever and for humans death is a part of life. Death comes in many different forms, but in the end all of these different forms still lead to only one thing death. Ethically there are two topics that always get everyone talking and is always a hot topic of debate. These two things are the ethical issues between natural death and physician-assisted death. These two forms of death both have supporters that back them and have valid reasons why they support either of the two. Throughout this essay the pros and cons of each will be discussed. Most humans don’t like the thought of death and tend to not want to discuss it because death is the end of the natural human life. Throughout history death has always been final and the thought of death scares many people. The way that some people die scares many people even more. Two ways that many people die are through natural death and physician-assisted death. These two topics come with a fair share of ethical issues that many people are for and against. Natural death occurs naturally and by naturally it means that there were no other things that contributed to the death of a person. No physician helped with the process and the human just died from maybe old age or any other complications that take place as humans age...

Comparing 'The Osage Firebird And A Life Painting Animals'

...“The Osage Firebird” by Sudipta Bardham- Quallenn “A Life Painting Animals” by Diana Childress “The Osage Firebird” by Sudipta Bardham- Quallenn, and “A Life Painting Animals” by Diana Childress are two short stories that both tell a story about a woman who had to overcome obstacles and barriers to become successful. In my opinion the story “The Osage Firebird” better develops the purpose. It states in the story that Betty Marie Tallcheif was almost “living in two different worlds.” This would be very challenging for her since she was a Native American going into the American world with being the first Indian ballerina. In the story “A Life Painting Animals” it states that Rosa Bonheur just painted all of her life and learned from her father...

Using anything they can to get DNA of the other person to see their positive and negative attributes. Mainly it is used to see whether they want to date them based of their DNA. Reproduction is done in two ways, “faith births” and “natural births”. Natural births is where Valids come from and Faith births is where invalids come from. The norm was Natural birth because parents wanted their kid to be good enough to receive their fathers name and to become a Valid. Though natural birth doesn’t come from intercourse it doesn’t have anywhere near the problems as birth from intercourse or known as faith births.

Problems

...be willing to accept them as such, one could just look at the order of life. Animals act intuitively in feeding and reproduction; the human anatomy contains a heart that pumps blood throughout the body to sustain life. Or, better yet, what about DNA or RNA? DNA and RNA are absolutely vital to the life of a human, and existence without DNA is impossible. However, atheists and those who deny the existence of design and purpose, cannot explain where DNA/RNA came from. The transcription of DNA to RNA is something that scientists admit cannot be numerically computed because of its complexity.[8] Would the existence, functioning, and transcription of DNA to RNA provide a basis for genuine indisputable design and purpose for McCloskey? If not, then what does? This is the problem with stating the need for genuine indisputable examples of design and purpose because who is the judge or standard of what is indisputable? McCloskey may look at the complexities of DNA to RNA and the order of life as natural progression of evolution. In fact, McCloskey implies that evolution displaces the need for a designer. I, however, disagree. One thing that evolution does is offers an explanation contrary to intelligent design regarding the scientific observations of the natural order of life. While evolution provides the scientific explanation of natural order, it does not explain the creation or ultimate beginning of such natural order. Could not a theist come back in reply to McCloskey and state that...

The Riddle of Inequality

...in the bible. People always wonder why some have more than others do; they wonder why this happens and how it can change. I believe that this riddle is natural and cannot be changed despite he best efforts of people. Tillich attributes this mystery of have's and have-nots to many factors. First is that if you were granted with inherited talents then you should use them in life to the best of your ability. But if you let them go to waste, then these talents will ultimately be taken away. It is unfair when things are taken away that we might have taken for granted due to lack of attention, such as, "...[the] intense joy and the presence of the mystery of life through the freshness of the young day or the glory of the dying day..." These things are only taken away because we do not pay enough attention to the simple beauty in life and in nature. Although all of these are examples of inequality, I do not agree with Tillich when he claims that this is due to the presence of the divine, by the choice of God. I believe inequality comes from ourselves. We may embrace, or else let it slip away. It is through our lack of conscientiousness that life becomes unequal.       I attribute the basic inequalities in nature as an effect of true nature, almost as far as survival of the fittest. Inequality is unfair but it is an aspect of life that people must deal with without an answer, without justification. When looking to God or any religious aspect for an answer you can only possibly answer...

The team will describe the properties of life on Earth and explain the theories for the genesis of life, including the theory of natural selection. Members will provide a brief description of the evolution of life and include a geological timescale that describes specific eras throughout the previous three billion plus years. The team will assess the possibilities of extraterrestrial life, and results will be presented. Describe the properties of life on Earth Properties of life on Earth are what define the word life. The properties of life consist of cells and reproduction, responses to the environment, growth and development, and evolution. Every living thing is collected through cells which make tissues and organs that make a living organism. All living organisms can produce such as humans, animals, bacteria, and plants called asexual reproduction. The responses of the living in the environment are through any changes occurring in “light, sound, heat, and chemical contact” through “eyes, ears, and taste buds” (Cliff’s notes, 2011, para. 3). Behavior is one way that all living organisms changes through the environment such as the food chain for one’s survival.
