Question

Match the following: 

• A. A-II, B-IV, C-III, D-I
• B. A-III, B-I, C-IV, D-II
• C. A-IV, B-I, C-II, D-III
• D. A-II, B-III, C-IV, D-I

Hint:

Familiarize yourself with enzyme classifications and their molecular components to better understand their mechanisms of action.

Answer 1

The Correct Option is C

Step 1: Peroxidase (A) is an enzyme that requires a prosthetic group for its activity. The prosthetic group is tightly bound to the enzyme, and hence the correct match is A-IV. 
Step 2: NAD+ (B) is a coenzyme that plays a crucial role in redox reactions. It serves as an electron carrier and is required for various enzymatic reactions. Therefore, B-I is the correct match. 
Step 3: Carboxypeptidase (C) is an enzyme that requires a metal ion for its catalytic activity. It is a type of apoenzyme + metal ion, making C-II the correct match. 
Step 4: Malate dehydrogenase (D) is an enzyme that requires a coenzyme for its activity. The coenzyme is essential for the enzyme's function, making D-III the correct match.
