During an investigation, enzyme activity is restored immediately after removing the inhibitor from the reaction mixture. The inhibitor is most likely

A. A reversible inhibitor
✓
B. An irreversible inhibitor
C. A heavy metal ion
D. A denaturing agent

📝 Explanation

Reversible inhibitors bind temporarily and can dissociate from the enzyme. Removing them restores enzyme activity. Irreversible inhibitors permanently inactivate the enzyme. Concept tested: Reversible vs. irreversible inhibition.
