The chemical processes by which cells produce the substances and energy needed to sustain life. As part of metabolism, organic compounds are broken down to provide heat and energy in the process called catabolism. Simpler molecules are also used to build more complex compounds like proteins for growth and repair of tissues as part of anabolism. Many metabolic processes are brought about by the action of enzymes. The overall speed at which an organism carries out its metabolic processes is termed its metabolic rate (or, when the organism is at rest, its basal metabolic rate). Birds, for example, have a high metabolic rate, since they are warm-blooded, and their usual method of locomotion, flight, requires large amounts of energy. Accordingly, birds usually need large amounts of high-quality, energy-rich foods such as seeds or meat, which they must eat frequently.

- The complex of physical and 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.
- The functioning of a specific substance, such as water, within the living body.

Metabolism
Mes"o*state\, n. [Meso- + Gr. ? to make to stand.] (Physiol.) A product of metabolic action. Note: Every mesostate is either an anastate or katastate, according as it is formed by an anabolic or katabolic process. See Metabolism.| Webster's Revised Unabridged Dictionary, © 1996, 1998 MICRA, Inc. |
Metabolism
Me*tab"o*lism\, n. (Physiol.) The act or process, by which living tissues or cells take up and convert into their own proper substance the nutritive material brought to them by the blood, or by which they transform their cell protoplasm into simpler substances, which are fitted either for excretion or for some special purpose, as in the manufacture of the digestive ferments. Hence, metabolism may be either constructive (anabolism), or destructive (katabolism).| Webster's Revised Unabridged Dictionary, © 1996, 1998 MICRA, Inc. |
Metabolism
Me*tab"o*lize\, v. t. & i. (Physiol.) To change by a metabolic process. See Metabolism.| Webster's Revised Unabridged Dictionary, © 1996, 1998 MICRA, Inc. |
Metabolism
Nu*tri"tion\, n. [Cf. F. nutrition. See Nutritious.]1. (Physiol.) In the broadest sense, a process or series of processes by which the living organism as a whole (or its component parts or organs) is maintained in its normal condition of life and growth. Note: In this wide sense it comprehends digestion, absorption, circulation, assimilation, etc., in fact all of the steps by which the nutritive matter of the food is fitted for incorporation with the different tissues, and the changes which it undergoes after its assimilation, prior to its excretion. See Metabolism. 2. (Physiol.) In a more limited sense, the process by which the living tissues take up, from the blood, matters necessary either for their repair or for the performance of their healthy functions. 3. That which nourishes; nutriment. Fixed like a plant, on his peculiar spot, To draw nutrition, propagate, and rot. --Pope.| Webster's Revised Unabridged Dictionary, © 1996, 1998 MICRA, Inc. |
Metabolism
Me*tab"o*lism\, n. (Biol.) The series of chemical changes which take place in an organism, by means of which food is manufactured and utilized and waste materials are eliminated.| Webster's Revised Unabridged Dictionary, © 1996, 1998 MICRA, Inc. |
