The incorrect statements regarding enzymes are:
(A) Enzymes are biocatalysts.
(B) Enzymes are non-specific and can catalyse different kinds of reactions.
(C) Most Enzymes are globular proteins.
(D) Enzyme - oxidase catalyses the hydrolysis of maltose into glucose.
Choose the correct answer from the option given below:
  1. (A)(B) and (C)
  2. (B)(B), (C) and (D)
  3. (C)(B) and (D)✓ Correct
  4. (D)(A), (B) and (C)

Answer: (C)

Solution

Enzymes are biocatalysts (A: true) that are highly substrate-specific, not non-specific (B: false as stated — this is one of the incorrect statements). Most enzymes are globular proteins (C: true). The hydrolysis of maltose to glucose is catalysed by maltase, not an oxidase (D: false — the second incorrect statement). The incorrect statements are (B) and (D).
