1. Regarding enzyme inhibitors, the primary characteristic of a competitive inhibitor is

A. Binding to the active site of the enzyme
✓
B. Binding permanently to the enzyme
C. Destroying the enzyme protein
D. Converting the enzyme into a substrate

📝 Explanation

Competitive inhibitors resemble the substrate and compete for the enzyme's active site. Increasing substrate concentration can overcome their effect. The other options describe irreversible inhibition or incorrect mechanisms. Concept tested: Competitive inhibition.
