1. The chemical processes occurring within a living cell or organism that are necessary for the maintenance of life. In metabolism some substances are broken down to yield energy for vital processes while other substances, necessary for life, are synthesized.
2. The processing of a specific substance within a living cell or organism: iodine metabolism.
1. (Biochemistry) the sum total of the chemical processes that occur in living organisms, resulting in growth, production of energy, elimination of waste material, etc. See anabolism, basal metabolism, catabolism
2. (Biochemistry) the sum total of the chemical processes affecting a particular substance in the body: carbohydrate metabolism; iodine metabolism.
[C19: from Greek metabolē change, from metaballein to change, from meta- + ballein to throw]
me•tab•o•lism(məˈtæb əˌlɪz əm)
the sum of the physical and chemical processes in an organism by which its substance is produced, maintained, and destroyed, and by which energy is made available. Compare anabolism, catabolism.
met•a•bol•ic (ˌmɛt əˈbɒl ɪk) adj.
The chemical processes by which cells produce the substances and energy needed to sustain life. In metabolism, organic compounds are broken down to provide heat and energy, while simpler molecules are used to build complex compounds like proteins for growth and repair of tissues. Many metabolic processes are brought about by the action of enzymes.
the chemical and physical processes in an organism by which protoplasm is produced, sustained, and then decomposed to make energy available. Also, Rare. metaboly. — metabolize, v.See also: Change
1. All of the chemical reactions taking place inside an organism.
