Anabolism is the constructive phase of metabolism in which simple substances are synthesized or bulit up into the complex materials of living tissue. This process requires energy in the form of ATP. Anabolism is necessary for body-building, growth, and repair. Example - Photosynthesis is an anabolic reaction since simple molecules like carbon diuoxide and water are used to build complex sugars.
Catabolism is the destructive phase of metabolism, in which complex molecules are broken down into simpler ones, often resulting in a release of energy. Here energy released is stored in the form of ATP.
Respiration is an example of a catabolic series of reactions. Here glucose is broken down by oxygen into simple molecules like water and carbon dioxide, with the release of energy.
A proper relation between anabolism and catabolism is essential for the maintenance of bodily homeostasis and dynamic equilibrium.
