Question

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)

Answer 1

The Correct Option is C

To identify the inaccurate statements about enzymes, each statement will be analyzed:

1. Statement A: Enzymes are biocatalysts.
   This statement is accurate. Enzymes function as biological catalysts, accelerating chemical reactions within living organisms without undergoing consumption.
2. Statement B: Enzymes are non-specific and can catalyse different kinds of reactions.
   This statement is inaccurate. Enzymes exhibit high specificity; each enzyme typically catalyzes a singular reaction type or acts upon a specific substrate due to the distinct conformation of its active site.
3. Statement C: Most Enzymes are globular proteins.
   This statement is accurate. Enzymes are predominantly composed of globular proteins, whose intricate three-dimensional structures are vital for their catalytic functions.
4. Statement D: Enzyme - oxidase catalyses the hydrolysis of maltose into glucose.
   This statement is inaccurate. Oxidases are enzymes involved in oxidation-reduction reactions, not hydrolysis. Maltase, not oxidase, catalyzes the hydrolysis of maltose into glucose.

Following the analysis, the erroneous statements are identified as (B) and (D).
Consequently, the correct response is: (B) and (D)
