Metabolism

The chemical processes associated with with living organisms is called Metabolism.It is usually divided into two parts; catabolism and anabolism.

Catabolism:

Catabolism is a process in which complex substances are decomposed into simple ones.With the release of energy, which becomes available for the organism's activity. In short, catabolism breakdown the organic matters and release energy that  and usually used to drive chemical reactions and anabolic reactions in the body.

Anabolism:

Anabolism involves in building up of complex substances with the absorption or storage of energy.The simpler substances are combined to form more complex molecules in as a result of anabolic reactions. Anabolic reactions need energy that usually comes from catabolic reactions. Therefore anabolic reactions build new molecules and store energy that stored in ATP

Metabolic reactions are usually under the control of enzymes, which are consequently of immense importance in chemistry of life. Metabolic processes are very similar throughout the plants and animal kingdoms. There are therefore corresponding similarities between the enzymes manufactured by organisms.
