Quizplus · Accepted Answer

Constitutive enzymes are always present in a cell, regardless of the amount of substrate present. In contrast, regulated enzymes are only synthesized in response to a specific stimulus or signal, and their presence varies depending on the conditions. Apoenzymes and holoenzymes refer to the inactive and active forms of an enzyme, respectively, and axoenzymes and endoenzymes are not commonly used terms in biochemistry.
