Question

All drugs block enzyme activity by occupying the active site before the substrate.

(a) True

(b) False

This question was addressed to me by my college professor while I was bunking the class.

This interesting question is from Drug-Target Interaction topic in portion Chemistry in Everyday Life of Chemistry – Class 12

Answer 1

Correct answer is (b) False

To elaborate: Drugs prevent the attachment of substrate to enzymes by two different ways. One is the competitive approach where it occupies the active site, and the other is non-competitive way in which it does not occupy the active site.
