catabolism (kətăb`əlĭz'əm), subdivision of metabolismmetabolism,
sum of all biochemical processes involved in life. Two subcategories of metabolism are anabolism, the building up of complex organic molecules from simpler precursors, and catabolism, the breakdown of complex substances into simpler molecules, often accompanied by

Large polymeric molecules such as polysaccharides, nucleic acids, and proteins are first split into their constituent monomeric units, such as amino acids, after which the monomers themselves can be broken down into such simple cellular metabolites as lactic acid, acetic acid, carbon dioxide, ammonia, and urea. The first set of reactions provides the cell with monomers with which it can construct new polymeric molecules. The second set of reactions usually involves the process of oxidation and is accompanied by a release of chemical free energy, not all of which is lost as heat, but is partially conserved through the coupled synthesis of adenosine triphosphateadenosine triphosphate
(ATP) , organic compound composed of adenine, the sugar ribose, and three phosphate groups. ATP serves as the major energy source within the cell to drive a number of biological processes such as photosynthesis, muscle contraction, and the synthesis of

Thus catabolism also provides the source of chemical energy necessary for the maintenance of the living cell.Catabolism a set of chemical processes constituting the reverse of anabolism. Catabolic processes are directed toward splitting the complexcompounds that form the structural elements of organs andtissues (proteins, nucleic acids, phospholipids) or that are depos-ited in the organs and tissues as reserve material (fat, glycogen).As a result of catabolism, complex compounds lose their specificproperties and are converted to substances that are partly uti-lized for biosynthesis and partly eliminated from the body (inter-mediate and final products of metabolism). catabolism[kə′tab·ə‚liz·əm] (biochemistry) That part of metabolism concerned with the breakdown of large protoplasmic molecules and tissues, often with the liberation of energy. catabolism, katabolism a metabolic process in which complex molecules are broken down into simple ones with the release of energy; destructive metabolism catabolismenUK

Compare: anabolism, metabolism[G. katabolē, a casting down]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.CatabolismA process of metabolism that breaks down complex substances into simple ones.Mentioned in: Interactionsca·tab·o·lism (kă-tab'ō-lizm) Breaking down in the body of complex chemical compounds into simpler ones.
