From The Collaborative International Dictionary of English v.0.48 :

  Metabolism \Me*tab"o*lism\, n. (Physiol.)
     1. 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 enzymes. Hence, metabolism may be either
        constructive ({anabolism), or destructive ({catabolism}).
        [1913 Webster]
     2. (Biol.) The series of chemical changes which take place in
