(d) Non-competitive Drugs are active site blocking

Question

Statements about Enzyme Inhibitor Drugs are given below:
(a) There are Competitive and Non-competitive inhibitor drugs.
(b) These can bind at the active sites and allosteric sites.
(c) Competitive Drugs are allosteric site blocking drugs.
(d) Non-competitive Drugs are active site blocking drugs.
Choose the correct answer from the options given below.
(A) (a), (d) only
(B) (a), (c) only
(C) (a), (b) only
(D) (a), (b), (c) only

Accepted Answer

(a), (b) only. Statements (a) and (b) are correct because enzyme inhibitors can indeed be classified into competitive and non-competitive types, and they can bind to both active and allosteric sites on enzymes. Statements (c) and (d) are incorrect as competitive inhibitors bind to active sites, while non-competitive inhibitors do not block the active site but rather bind elsewhere.
