catabolism

The breakdown of complex body molecules to simpler forms, as when muscle protein breaks down to amino acids or fats to glycerol and fatty acids. The opposite process is called anabolism and both processes are encompassed in METABOLISM.

catabolism

or

katabolism

a type of METABOLISM in which biochemical processes taking place in a cell result in the breaking down of complex compounds into simpler ones to release energy. Catabolism usually involves a series of step-by-step reactions, each catalysed by its own enzyme, for example, AEROBIC RESPIRATION.
