Question

Match List-I with List-II.

List-I	List-II
A. Albumin B. Collagen C. Myosin D. Hemoglobin	I. Structural (Muscle) II. Transport and binding III. Blood plasma protein IV. Structural (connective tissue)

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

Hint:

Albumin → transport, Collagen → structure, Myosin → muscle, Hemoglobin → blood.

Answer 1

The Correct Option is B

Concept: Proteins perform diverse biological functions including structural roles, transport, and enzymatic activities.

Step 1: Albumin (A).

• Transport protein in blood So, A $\rightarrow$ II.

Step 2: Collagen (B).

• Structural protein in connective tissue So, B $\rightarrow$ IV.

Step 3: Myosin (C).

• Muscle protein responsible for contraction So, C $\rightarrow$ I.

Step 4: Hemoglobin (D).

• Blood protein carrying oxygen So, D $\rightarrow$ III.

Step 5: Final matching. \[ A-II,\; B-IV,\; C-I,\; D-III \] Final Conclusion:
Option (2) is correct.
