Question

Match List-I with List-II. List-I: A. Coenzyme A, B. Cobamide coenzymes, C. Flavin Mononucleotide, D. Biocytin. List-II: I. Hydrogen atoms, II. Carbon Dioxide, III. Acyl group, IV. Alkyl group.

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

Hint:

Remember: Coenzyme A carries acyl groups, FMN carries hydrogen/electrons, and biocytin carries carbon dioxide.

Answer 1

The Correct Option is D

Concept:
Coenzymes help enzymes by carrying specific chemical groups during biochemical reactions.

Step 1: Match Coenzyme A.
Coenzyme A carries acyl groups during metabolism. \[ A \rightarrow III \]

Step 2: Match Cobamide coenzymes.
Cobamide coenzymes, such as vitamin \(B_{12}\) derivatives, are involved in transfer of alkyl groups. \[ B \rightarrow IV \]

Step 3: Match Flavin Mononucleotide.
Flavin mononucleotide is involved in oxidation-reduction reactions and carries hydrogen atoms or electrons. \[ C \rightarrow I \]

Step 4: Match Biocytin.
Biocytin is involved in carboxylation reactions and carries carbon dioxide. \[ D \rightarrow II \] Therefore, the correct matching is: \[ A-III,\ B-IV,\ C-I,\ D-II \] \[ \therefore \text{Correct Answer is (D)} \]
