C) a cofactor
D) a regulator

Question

Quizplus · Accepted Answer

A regulator refers to a molecule that can bind reversibly to an allosteric enzyme and modulate its activity. A zymogen refers to an inactive precursor of an enzyme that requires activation. An isozyme refers to different forms of an enzyme that have different amino acid sequences but catalyze the same reaction. A cofactor refers to a non-protein molecule that is required for enzyme activity, such as a metal ion or a coenzyme.
