M1: the role of energy in the body
ATP (Adenosine triphosphate) is a source of energy for the body and the only form of usable energy in there body. ATP is what converts the energy found in food to energy our cells can use to allow them to function properly. The chemical energy of ATP can be transferred to other cellular materials or be converted to mechanical energy. The energy needed by the body is stored in the high energy bond, to release this energy and allow muscular movement, an enzyme called ATPase breaks this bond, and these leave two molecules of phosphate attached to the adenosine (adenosine diphosphate) and a free phosphate molecule. The food we eat, in the form of carbohydrates, fats and proteins, is used as fuel for reactions in the body that make us 'alive'. To utilise these fuels for muscle action, the body converts them to a common 'energy currency', called adenosine tri-phosphate (ATP), once converted to ATP, it can lose its chemical energy and it becomes ADP. We all need energy to move our body. In order to get energy, we need to eat right, then put ourselves to motivate for every day. If we have no energy in our body, we are dead by now. Glucose is a simple sugar that provides the body with its primary source of energy. This type of sugar comes from digesting carbohydrates into a chemical that the body can easily convert to energy.

The carbohydrate is broken down into glucose by enzymes in precise stages that allow energy to be released so that it can be used by the person, when glucose levels in the bloodstream aren't properly regulated, a person can develop a serious condition, such as diabetes. The process involves the random motion of oxygen and glucose from regions of higher concentration First the oxygen must diffuse from the alveolus into the capillaries. It is able to do this because the capillaries are permeable to oxygen. After it

...physiology Unit 5.4 P4 M1 D1 P4- Explain the Physiology of Two Named Body Systems in Relation to Energy Metabolism in the Body M1-Discuss the Roles of Energy in the Body In this assignment I will be explaining the physiology of the cardiovascular system and the respiratory system. Whilst explaining the two body systems I will be explaining energy production, process of cellular respiration, the role of enzymes within these body systems, the way that these systems absorb food and the products of digestion. The Cardiovascular System The heart pumps the blood around the body through the blood vessels which is made of mostly veins and capillaries. The blood carries the dissolved oxygen around the bodily cells, whilst carrying the dissolved oxygen the blood removes the waste and the other products from respiration. The body’s blood pressure has to be maintained. The blood distributes heat around the body along with hormones, nutrients, salts, enzymes and urea. The cardiovascular system transports simple molecules and materials to the liver and the body cells via the blood stream. This happens through the hearts pumping actions. The Respiratory System The respiratory system always refreshes oxygen within the lungs, it gets rid of the waste products like carbon dioxide and water, and this is done throughout actions like breathing. The dissolved oxygen passes through the alveolar walls into the bloodstream; this is then transported into the cells. Body cells are persistently...

...M1: This report will explain the role of energy in the body. It will include the different forms of energy in the body, the two laws of energy, anabolism and catabolism and the role of the cardiovascular system and the respiratory system in energy metabolism. Energy is defined in the capacity to do work. Energy is needed for all of the functions of the body, we need it for all the different activities that we do, and for chemical reactions within our body. Some of the things that energy is essential for are; tissue growth; tissue repair; chemical reactions inside the cells, storing nutrients and digestion. The forms of energy comes in three; kinetic energy, chemical energy and potential energy. Chemical energy is the main source of energy for our body. Chemical energy is the bond which unites atoms or molecules with each other. When a new bond is produced between two atoms, energy is needed for its formation and this is mainly in the form of heat but can be light or electrical energy. When a bond is broken and the atoms are free, the energy in the bond is released. Potential energy is stored energy, which is then converted into kinetic energy. Kinetic energy is the energy of motion. There are a few types of different energy and these are: chemical, heat, sound, light, electrical and mechanical. There are ‘two laws’ of energy, the first law states that energy cannot be created or destroyed, this is the conservation law. The second law states that energy can be transformed...

The Analysis of Lipids Determination of Fat by Soxhlet Extraction

...molecular organic compounds, composed largely of carbon, oxygen and hydrogen and are essential for cell growth. Lipids are non-soluble in water and combine with carbohydrates and proteins to form the majority of all plant and animal cells. Lipids are transported through the body attached to protein and are an important element of food. Lipids are the third major micronutrient required for the body after carbohydrates and protein. Lipids are also a medical term for ‘fat’ and though all fats are lipids, not all lipids are fats. Lipids have many roles within the body, one of its main duties is to transport, absorb and digest the fat soluble vitamins A,D,E and K. They provide the most energy to the body, are used for energy storage, cell membrane development, and they protect vital organs. Other major purposes are that they insulate layers under the skin, provide vitamins, essential nutrients and fatty acids in the body. Fatty acids cannot be made by the body and are therefore fat is essential in the diet. In many foods the lipid components add to flavor perception, texture, mouth feel and appearance. (Intro to food Nutrition handout, 15/02/11) It is important to remember that although fat is essential, the body only requires 30% of daily calorie intake to come from fat. Over consumption of fats can lead to weight gain and health problems. There are many different types of fat some good and some bad. Polyunsaturated and Monounsaturated are good fats and raise healthy cholesterol...

...M1) Discuss the role of energy in the body In this assignment, I will be discussing the role of energy in the body. Energy forms, energy metabolism and any reactions will be discussed during the course of this assignment. Energy is used up at all times for body processes and is supplied from an individual’s diet, in the form of calories. Within the human body, energy is needed for a variety of reasons. Firstly, without energy humans will be unable to function correctly, preventing them from doing absolutely anything. For example, humans will not be able to communicate as they will have no energy to talk. Human muscles will not be able to function as they are energy-less, preventing them from performing simple everyday tasks (Moonie, 2010). Energy is needed to extract oxygen from certain areas within the human body and release it into the bloodstream. Furthermore, the human body needs energy to circulate blood and tissue fluid around the body. Energy is necessary is for breathing, taking in oxygen and making new tissues for growth and repair. Energy also transmits nerve impulses so that the human body is able to respond to changes within the environment in order to build different complex molecules, such as enzymes and hormones. This is to form the simple molecules produced after the digestion of food (Aldworth, 2010). Without energy stored in human bodies, humans would not be able to function properly. Energy comes from: fats, carbohydrates and proteins in the food that individuals...

...will then be able to apply this understanding and make recommendations to improve the nutritional health of an individual. Unit introduction This unit builds on learner understanding of the principles introduced in Unit 5: Fundamentals of Anatomy and Physiology for Health and Social Care. Improvements in the diet of individuals are increasingly being recognised as a significant factor in maintaining, or effecting improvements, in overall health. It is therefore important that people working in the health and social care sectors, or those who are responsible for the wellbeing of others, have a good understanding of nutrition and diet. This unit gives learners an understanding of nutrition from a science-based perspective and of the role that food plays in social contexts. The unit may also provide useful underpinning knowledge for the study of food hygiene and practical culinary skills. Learners will explore concepts of nutrition using the language of nutritional science. Different aspects of nutritional health will be defined and routine ways of measuring this explored. Other aspects of nutritional data will involve describing the general principles on which nutritional requirements are determined in the UK and how information on the nutrient content of foods can be retrieved. Learners will also explore how the nutritional value of foods may be affected by food processing. The function and sources of the main nutrients will be investigated in relation to the contribution...

...2014 Unit 21: Human Resource Management 2014 Learning outcomes and assessment criteria Recruiting and retaining staff of the right caliber contributes to the achievement of organizational purposes. Staff must make a valued contribution to the work of the organization. Eventually they will leave, more often than not because they find alternative employment or retire. Occasionally, however, employment has to be terminated. This unit considers how human resource management deals with these aspects of working. However, the focus of human resource management has moved beyond personnel management towards a more proactive approach that, in addition to the traditional roles associated with staff management, also considers how to get the best people and the best out of people so that they work in roles and ways that are closely aligned to organizational objectives. This often leads to the assertion by many senior managers that 'Our employees are our most valuable resource‘. Human resource management takes place against a background of organizational needs, policies and procedures that are themselves shaped by legal and regulatory requirements....

...named body systems in relation to energy metabolism in the body. M1- Discuss the role of energy in the body. The Conservation of energy The first law of thermodynamics, is sometimes known as the conservation of energy, this states that: ‘Energy can be transformed (changed from one form to another), but cannot be created or destroyed’. (Moonie, 2010) The second form may not be of use or be capable of being measured. Forms of energy within the body Through the body there are five different forms of energy which exists. These are chemical, kinetic, electrical, elastic and thermal .Energy can be found in several forms and chemical energy is the most common. The energy that is in the chemical bond unites atoms or molecules with each other. When a new bond is made between two atoms, energy is needed for its formation and this is usually in the form of heat, light an electrical energy could be used. If the bond is broken and the atoms are released, the energy in the bond is released. Elastic energy is found with the arteries. The middle layer of the tissue (tunica media) which is within the artery wall lining has elastic tissues in. The elastic tissue lets the artery walls to be able to stretch and recoil which helps prevents damage from the high pressure blood flowing through them. By allowing the stretch of the artery this is causing the elastic energy. This kind of energy is known as the ‘potential energy’. Thermal energy is one of the five forms of energy which...
