BIO NMDCAT Inhibitors

nmdcat.online July 13, 2026

During an enzyme-catalyzed reaction, the addition of a non-competitive inhibitor primarily causes

A. A conformational change in the enzyme

✓

B. Complete destruction of the substrate

C. Permanent denaturation of all proteins

D. Increased formation of enzyme-substrate complexes

📝 Explanation

Non-competitive inhibitors bind at an allosteric site and alter the enzyme's three-dimensional shape, reducing catalytic efficiency. They do not necessarily destroy the substrate or all proteins. Concept tested: Mechanism of non-competitive inhibition.
