Answer: METABOLISM which involves ANABOLISM and CATABOLISM is defined as the totality of processes carried out by an organism in order to grow,develop and sustain life.
It is the process by which the body changes the food we eat to energy so that the body can use energy to perform activities the contribute to its growth and development.
Metabolism occurs mainly in the liver because of the presence of enzymes that are necessary for the metabolism and it involves two (2) distinct activities that go on at the same time.
ANABOLISM involves building up of body tissues and storage of energy while CATABOLISM has to do with the breaking down of body tissues and also the breaking down of stored energy inorder to get more fuel to facilitate body functions.
Digestion is a form of CATABOLIC activity.
Just as catabolism is described above, digestive processes breaks down the complex foods we eat into forms that smaller and usable by the body.Digestive processes breaks down proteins into amino acids,turns carbohydrates into simple sugars like glucose and breaks fats down into fatty acids.
These end products( amino acids,simple sugars and fatty acids)
are then taken up by the cells in the body to aid in the growth and development of the body.
