Dynamic State of Body Constituents - Concept of Metabolism

Metabolism: This is the sum total of all the chemical reactions occur in living beings in an olderly fashion. Metabolism is made up of anabolism and catabolism.

Anabolism: Anabolism is the sum total of those reaction which build up complex substances from simpler ones. Example of anabolism are glycogen from glucose, proteins from amino acids. Energy is stored in the components that are use for future purpose. Anabolism is also called constructive metabolism as simple components are associated together to form complex substances.

Catabolism: This is the sum total of all breakdown reactions that split the complex substances into simpler ones. This is called destructive process as the complex substances degraded into simpler form and during this transformation they release the energy that is used by the body for different purposes. The main purpose is to metabolise the substances to release energy and transform to a simpler form for the absorption by the body. Absorption of the simpler substances done by blood, intestinal cells etc.


Examples of the catabolic process are-

1. Formation of glucose from glycogen.

2. Formation of amino acids from peptides.

3. Respiration is an example of catabolism process by which energy released from the food.


Major example of anabolism and catabolism process are photosynthesis and respiration. Energy accumulation occurs in the first and released in the later.
