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:
  1. (A)(A), (D) only
  2. (B)(A), (C) only
  3. (C)(A), (B) only✓ Correct
  4. (D)(A), (B), (C) only

Answer: (C)

Solution

Statement (A) is correct: enzyme inhibitors can be competitive or non-competitive. Statement (B) is correct: competitive inhibitors bind at the active site, while non-competitive inhibitors bind at allosteric sites. Statement (C) is incorrect: competitive drugs block the active site, not the allosteric site. Statement (D) is incorrect: non-competitive drugs bind at allosteric sites, not the active site. Therefore, only statements (A) and (B) are correct.
