Q1How does a non‑competitive inhibitor affect enzyme activity?

A. Binds an allosteric site, altering active‑site shape ✓ Correct Answer

B. Binds the active site, blocking substrate

C. Denatures the enzyme

D. Acts as a coenzyme, increasing rate

💡 Explanation: Non‑competitive inhibitors bind to an allosteric site, changing the enzyme’s shape so the active site no longer works.
