Me*tab"o*lism, n. (Physiol.)
Definition: 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).
