Question

Quizplus · Accepted Answer

A zymogen is an inactive precursor of an enzyme that can be converted into an active enzyme by a chemical change, such as the cleavage of a peptide bond. Examples include pepsinogen, trypsinogen, and chymotrypsinogen. The other options, allosteric enzyme, cofactor, and isozyme, do not necessarily require a chemical change to become active.
