Question

Quizplus · Accepted Answer

Zymogens are inactive precursors of enzymes that require a biochemical change to become active. Pepsinogen and procarboxypeptidase are examples of zymogens, which are activated to become pepsin and carboxypeptidase, respectively. The T-form of ACTase is not a zymogen but a form of the enzyme aspartate carbamoyltransferase, which is involved in regulatory mechanisms rather than being an inactive precursor requiring activation.
