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.

Catabolism

A process of metabolism that breaks down complex substances into simple ones.
Mentioned in: Interactions

metabolism

continuous series of chemical processes in the living body by which life is maintained. Nutrients and tissues are broken down (catabolism), releasing energy which is utilized in the creation of new substances for growth and rebuilding (anabolism). metabolite any substance produced by a metabolic process. See also energy systems.

catabolism

metabolic processes breaking down complex compounds into simpler forms, and release of energy (opposite : anabolism)

catabolism (k·taˑ·bō·li·zm),

n process during metabolism where cells break down complex substances into simple compounds.

ca·tab·o·lism

(kă-tab'ō-lizm)
Breaking down in the body of complex chemical compounds into simpler ones.
[G. katabolē, a casting down]

catabolism (kətab´ōlizəm),

n the destructive processes (opposite of the anabolic-metabolic processes) by which complex substances are converted into more simple compounds. A proper relation between anabolism and catabolism is essential for the maintenance of bodily homeostasis and dynamic equilibrium.
catabolism of energy,
n the dissipation of energy in living tissues as work or heat (one phase being metabolism, the other being anabolism).
catabolism of substance,
n the destructive metabolism; the conversion of living tissues into a lower state of organization and ultimately into waste products.

catabolism

any destructive process by which complex substances are converted by living cells into simpler compounds, with release of energy. See also metabolism.
