<physiology> Term used by physiologists to describe the process of breathing and by biochemists to describe the intracellular oxidation of substrates coupled with production of ATP and oxidized coenzymes (NAD and FAD).

This form of respiration may be anaerobic as in glycolysis or aerobic in the case of oxidations operating via the tricarboxylic acid cycle and the electron transport chain.
