Metabolism
Metabolism or metabolism - a set of chemical reactions occurring in living organisms. Metabolism is divided into two branches: catabolism, which includes the reactions of the splitting of complex organic substances to the simplest, which is accompanied by their oxidation and the release of useful energy, and anabolism is the reaction of synthesis of the necessary cells of substances in which the energy obtained in catabolic reactions is used. Almost all metabolic reactions are accelerated by enzymes - catalysts of protein nature.
