Question

Match LIST-I with LIST-II

Choose the correct answer from the options given below:

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

Hint:

Associate keywords with each vitamin: Biotin $\rightarrow$ Coenzyme/Carboxylation, B12 $\rightarrow$ Red Blood Cells/DNA, C $\rightarrow$ Collagen/Scurvy, K $\rightarrow$ Klotting (clotting).

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
This question requires matching common vitamins (LIST-I) with their major functions in the human body (LIST-II).
Step 2: Detailed Explanation:
Let's determine the primary function for each vitamin listed:


A. B7 (Biotin): Biotin is a crucial coenzyme for carboxylase enzymes, which are involved in synthesizing fatty acids, synthesizing isoleucine and valine, and in gluconeogenesis. This broadly fits with III. Coenzyme in synthesis of fat, glycogen and amino acids.

B. B12 (Cobalamin): Vitamin B12 is essential for DNA synthesis, and thus for the maturation of red blood cells in the bone marrow and the production of nucleic acids. This matches with IV. Production of nucleic acids and red blood cells.

C. C (Ascorbic acid): Vitamin C is a required cofactor for enzymes that hydroxylate proline and lysine residues during the synthesis of collagen, the main structural protein in connective tissues. This matches with I. Used in collagen synthesis.

D. K (Phylloquinone): Vitamin K is essential for the synthesis of several proteins required for blood coagulation (clotting factors) in the liver. This matches with II. Important in blood clotting.

Step 3: Final Answer:
The correct matching is A-III, B-IV, C-I, D-II. This corresponds to option (D).
