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:
- a
(B) and (C)
- b
(B), (C) and (D)
- c✓
(B) and (D)
- d
(A), (B) and (C)
(B) and (D)
Step 1: Enzyme Definition — Enzymes are biological catalysts that are highly specific to both the substrate and the type of reaction they catalyze.
Step 2: Structural and Specificity Check — Most enzymes are indeed globular proteins. Statement (B), claiming they are non-specific, is incorrect.
Step 3: Identifying the Maltose Enzyme — Maltose is converted into glucose by the enzyme , not oxidase. Thus, statement (D) is also incorrect. Choice (c) is correct.
Key Point: Enzyme specificity is often described by the "lock and key" or "induced fit" models.
