Question

With respect to drug-enzyme interaction, identify the wrong statement.

(A) Competitive inhibitor binds to the enzyme’s active site
(B) Allosteric inhibitor competes with the enzyme’s active site
(C) Allosteric inhibitor changes the enzyme’s active site
(D) Non-Competitive inhibitor binds to the allosteric site

Prashant Kotian · Accepted Answer

Correct answer: C) ALLOSTERIC INHIBITOR CHANGES THE ENZYME’S ACTIVE SITE. Some drug do not bind to the Enzyme's active site. These hind to a different site of enzyme which called allosteric site. This binding of inhibitor at allosteric site changes the shape of the active site in such a way that substrate cannot recognize it. Such inhibitor is known as Non-competitive inhibitor.
