A crucial characteristic of enzyme cofactors is that they

A. Are always tightly bound prosthetic groups like heme
B. Are exclusively large globular proteins containing multiple domains
C. Are non-protein chemical compounds that are essential for the catalytic activity
✓
D. Function as allosteric inhibitors by binding to a regulatory subunit

📝 Explanation

Cofactors are non-protein components (metal ions or coenzymes) required for the activity of many enzymes, distinguishing simple from conjugated enzymes.
