P4: Explain the physiology of two named body systems in relation to energy metabolism in the body
In your role as a health and social care professional in a respite care home you have been asked to prepare a booklet to explain to your client group how the body requires and uses energy.
You should produce an information booklet that gives an overview of how energy is produced and utilised in the body.

You booklet should include information on:

* Energy forms * Energy laws * Why the body needs energy and where does it come from. * An explanation of the physiology of two named body system, and their role in the utilisation of energy in the body. An examples of 2 systems the you could discuss are as

Discuss the role of energy in the body – digestive system Analyse how two body systems inter-relate to perform a named function

Metabolism is a chemical process that converts fuel from food into energy needed for the body’s activities. For example, thinking, running and jumping etc. are all an example of the bodies activities.

Catabolism is the breakdown of larger molecules into smaller units to produce energy. In the digestive system, large substances such as molecules of fats and oils are broken down by an Enzyme called lipases into fatty acids, which is used and stored as energy. For example, when an athletic swimmer swims for a long time, they are due to run out of energy because they naturally get exhausted; hence, the body tends to use the stored energy in the muscles (fatty acids) to get the athlete energised again.

Also, large substances such as, proteins are broken down by enzymes called proteases into amino acids, which is used and stored as energy. An example of this is; when the body gets exhausted the fuel which is converted from the protein is used as energy and also to repair worn out tissues to keep the body healthy and energised. It also stimulates the immune system and aids the body in ATP production.
