P4- Explain the physiology of two named body system in relation to energy metabolism in the body
M1- Discuss the role of energy in the body
D1- analyse how two body systems interrelate to perform a named function/functions

1. Energy
Energy is the strength and vitality required for sustained physical or mental activity.
Body growth, development and functioning are some of the vital and fundamental aspects of life. They cannot be explained without referring to energy: fuel of life is dependent on energy transformations. Our foods bring us the vital energy that our body is burning throughout the day.

2. Role of energy in the body
Metabolism is a collection of chemical reactions that takes place in the body's cells. Metabolism converts the fuel in the food we eat into the energy needed to power everything we do, from moving to thinking to growing. Specific proteins in the body control the chemical reactions of metabolism, and each chemical reaction is coordinated with other body functions. Thousands of metabolic reactions happen at the same time all regulated by the body to keep our cells healthy and working.
The process of metabolism is really a balancing act involving two kinds of activities that go on at the same time: the building up of body tissues and energy stores and the breaking down of body tissues and energy stores to generate more fuel for body functions:
Anabolism is all about building and storing: It supports the growth of new cells, the maintenance of body tissues, and the storage of energy for use in the future. During anabolism, small molecules are changed into larger, more complex molecules of carbohydrate, protein, and fat.
Catabolism is the process that produces the energy required for all activity in the cells. In this process, cells break down large molecules (mostly carbohydrates and fats) to release energy. This energy release provides...
