Explain The Three Macromolecules That Provide Us With Energy

Submitted By
Words 78
Pages 1
The three macromolecules that provide us with energy are carbohydrates, proteins, and lipids. Carbohydrates is like the gas of a car: it provides fuel for our cells to use. For example, bread has a lot of carbohydrates and fibers. Our digestive system digests the bread’s carbohydrates into glucose, which provides energy for our organs, tissues, and cells. Fibers are a special type of carbohydrate that surprisingly doesn’t provide us with cellular energy; instead, they improve our digestive...

...power in the microworld or when objects travel at extremely high speeds, much higher than we are capable of propelling ordinary objects (except in particle accelerators). In this chapter we continue our study of one-dimensional motion in three “case studies” of interesting example applications. The goal here is to see the power of Newton’s laws as well as to learn some interesting ideas about various types of motion along a single direction. We gain some valuable insights and tools so that when we generalize to study the motion of objects in the real three-dimensional world we are well prepared for that undertaking. The case studies in this chapter include motion when the net force is constant (we study the local gravitational force near the Earth), one-dimensional motion of an object in a fluid (where we show that there are frictional forces that vary with time), and the oscillatory motion of an object attached to a spring. After learning something about springs, we next consider the deformation of an elastic solid and the phenomenon of viscoelasticity. This is a topic of special interest in the study of structural biomolecules such as bone and blood vessels. We conclude the chapter with a discussion of the structure and dynamics of macromolecules, specifically illustrating how to apply Newton’s second law to the difficult problem of determining the molecular motions (here in one dimension) of the constituent atoms of a protein. 1.

...and other radiation by matter, as related to the dependence of these processes on the wavelength of the radiation. More recently, the definition has been expanded to include the study of the interactions between particles such as electrons, protons, and ions, as well as their interaction with other particles as a function of their collision energy. Spectroscopic analysis has been crucial in the development of the most fundamental theories in physics, including quantum mechanics, the special and general theories of relativity, and quantum electrodynamics. Spectroscopy, as applied to high-energy collisions, has been a key tool in developing scientific understanding not only of the electromagnetic force but also of the strong and weak nuclear forces. The basic principle shared by all spectroscopic techniques is to shine a beam of electromagnetic radiation onto a sample, and observe how it responds to such a stimulus. The response is usually recorded as a function of radiation wavelength. A plot of the response as a function of wavelength is referred to as a spectrum. Electromagnetic radiation consists of discrete packets of energy, which call photons. A photon consists of an oscillating electric field component, E, and an oscillating magnetic field component, M. The electric and magnetic fields are...

Biological Molecules An introduction to the chemistry behind biomolecules What is biochemistry? Well, it’s the study of biology at a molecular level. So the emphasis of this unit is the biological significance of chemical molecules. As part of the course, there are six biological molecules that you need to know about: CH2OH Carbohydrates O H H OH OH These molecules are one of many vital to life. They are used for energy (for both storing and supplying energy), and in some cases can be used structurally, such as cellulose Lipids H O H H C H H C H H C O C O O C O O These come in many varieties: fats, oils, cholesterol, steroids, and more, and have uses in cellular membranes, insulating and protecting, and also act as a minor energy supply C H Proteins Proteins have several uses, such as for transport and structure; but they are also the basic components of all enzymes, hormones, antibodies, haemoglobin, ribosomes, and many more materials Water H O H Another essential life component, this is the most important content of many reactions forming most of these molecules, and also metabolic reactions; water is also an essential structural component in plants, and in the diet of animals Nucleic acids These are responsible for the formation of both DNA and all forms of RNA molecules, consisting of individual nucleotides Enzymes ...

...carbohydrate is a sugar molecule, a simple union of carbon, hydrogen, and oxygen. Starches and fibers are essentially chains of sugar molecules. Some contain hundreds of sugars. Some chains are straight, others branch wildly. Carbohydrates were once grouped into two main categories. Simple carbohydrates included sugars such as fruit sugar (fructose), corn or grape sugar (dextrose or glucose), and table sugar (sucrose). Complex carbohydrates included everything made of three or more linked sugars. Complex carbohydrates were thought to be the healthiest to eat, while simple carbohydrates weren’t so great. It turns out that the picture is more complicated than that. The digestive system handles all carbohydrates in much the same way—it breaks them down (or tries to break them down) into single sugar molecules, since only these are small enough to cross into the bloodstream. It also converts most digestible carbohydrates into glucose (also known as blood sugar), because cells are designed to use this as a universal energy source. Fiber is an exception. It is put together in such a way that it can’t be broken down into sugar molecules, and so it passes through the body undigested. Fiber comes in two varieties: soluble fiber dissolves in water, while insoluble fiber does not. Although neither type nourishes the body, they promote health in many ways. Soluble fiber binds to fatty substances in the intestines and carries them out as a waste, thus...

...Book 3 - Technology, use and potentialities of Latin American starchy tubers Chapter 18 Starch-based plastics Olivier Vilpoux1 & Luc Averous.2 18.1. Introduction Brazil disposes of approximately 240,000 tons of waste per day, an amount lower than that in the USA (607,000 t./day), but fairly above those in countries such as Germany (85,000 t./day) and Sweden (10,400 t./day). Of that total, a large amount goes to open waste deposits. Only a small quantity is disposed of in appropriate places. A city like São Paulo spends, per day, US$ 300,000 with waste. According to the Instituto de Pesquisas Tecnológicas – IPT (Institute of Technological Research), only few municipalities have specific teams and public policies engaged in dealing with the waste. When it is not treated, waste becomes a serious sanitary problem, since it exposes the community to illnesses like diarrhea, amebiasis, and parasitosis, apart from contaminating the soil, waters and water tables. Among solutions, there are the creation of sanitary landfills in appropriate places, adoption of selective collecting and recycling programs, conducting of campaigns with the aim of both making society conscious about the problem and demanding a greater participation of government authorities (Editora Abril, 2002). The manufacturing of biodegradable material offers an interesting solution for plastic materials. Like it happens with organic residues, such as foodstuff, elimination of biodegradable......

...Science Content Standards A Message from the State Board of Education and the State Superintendent of Public Instruction. In 1998 California adopted academically rigorous content standards in science. The adoption of standards in each core subject area marked a turning point in the education reform movement that began in 1983 with the report A Nation at Risk: The Imperative for Educational Reform, by the National Commission on Excellence in Education. Until then, the reform movement had focused on important but largely structural improvements, such as more instructional time, minimum course requirements for high school diplomas, and an emphasis on local planning efforts to promote efficiency and effectiveness. The desire to improve student achievement was there, but the focus on content-that is, a comprehensive, specific vision of what students actually needed to know and be able to do-was lacking. Standards are a bold initiative. Through content standards in the core subjects, California began to redefine the state’s role in public education. For the first time, the knowledge and skills that students needed to acquire were explicitly stated for the most part by grade level, although science standards at the high school level were organized by discipline. The standards are rigorous. Students who master this content are on a par with those in the best educational systems in other states and nations. The content is attainable by all students, given sufficient time, except for......
