catabolism

 [kah-tab´o-lizm]
any destructive process by which complex substances are converted by living cells into simpler compounds, with release of energy; the opposite of anabolism. See also metabolism. adj., adj catabol´ic.

ca·tab·o·lism

(kă-tab'ō-lizm),
1. The breaking down in the body of complex chemical compounds into simpler ones (for example, glycogen to CO2 and H2O), often accompanied by the liberation of energy.
2. The sum of all degradative processes.
Synonym(s): dissimilation (2)
Compare: anabolism, metabolism.
[G. katabolē, a casting down]

catabolism

(kə-tăb′ə-lĭz′əm)
n.
The metabolic breakdown of complex molecules into simpler ones, often resulting in a release of energy.

catabolism

[kətab′əliz′əm]
Etymology: Gk, kata + ballein, to throw
a metabolic process in which complex substances are broken down by living cells into simple compounds. The process liberates energy for use in work, energy storage, or heat production. Carbon dioxide and water are produced, as well as energy. Compare anabolism. catabolic, adj.

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.

A process of metabolism that breaks down complex substances into simple ones.
