Question

Match List I (Molecules) with List II (Properties/Location):

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

Hint:

Membrane = Water-soluble/Adrenergic; Nucleus = Thyroid; Endothelial = Nitric Oxide.

Answer 1

The Correct Option is B

Step 1--3: Analysis
Water-soluble hormones activate secondary messengers like cAMP (A-II). Nitric oxide activates the endothelial lining (B-III). Thyroid hormone receptors are in the nucleus (C-I). Adrenergic receptors are on the cell membrane (D-IV).

Step 4: Conclusion
The matches are A-II, B-III, C-I, D-IV.

Final Answer: (B)
