M1- Discuss the role of energy in the body
In our bodies we need energy so that we could do things that are possible such as; move our muscles, talk and all the other things that we do. Without energy all humans would be useless not being able to do anything. Energy is needed to extract the oxygen from the areas in our bodies and diffuse it into our bloodstream. As warm blooded we can only digest food and function if our bodies are at a certain temperature and have enough energy, and energy is required for this. We need energy to move our muscles which also only operate when they are warm. Coldblooded humans use the energy from the environment as well as from their food. Energy is the capacity to do work in our bodies. That means doing everything that a body needs to do to stay alive and to grow: pumping ions across membranes, making new proteins, making new lipids, making hormones, making new cells, neural function, contracting muscles, replacing damaged or worn-out components, absorbing nutrients, excreting wastes and pumping blood
-Supplying enough energy to support the many functions of the body at work and play is one of the chief functions of food. This energy comes from the fats, carbohydrates, and proteins in the food you eat. Of the three, fat is the most concentrated source of energy because it furnishes more than twice as much energy for a given weight as protein or carbohydrate. The energy requirement for a person is divided into two parts: basal metabolic requirements and energy required for activity. Basal metabolic rate is the heat eliminated from the body at rest when temperature is normal. An average person requires 2000-2400 Calories per day while a large man doing heavy work may require up to 6000 Calories per day. The three main classes of food provide the following amount of energy: carbohydrates and proteins provide about 4 Calories per gram; fats provide about 9 Calories per gram. When you choose foods that furnish more energy, or
