NEET Zoology Muscle Contraction Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Myosin | (i) Involuntary muscle |
| (b) Tropomyosin | (ii) Thick filament |
| (c) Cardiac muscle | (iii) Active site masking |
| (d) Smooth muscle | (iv) Striated muscle |
a-ii, b-iii, c-iv, d-i
a-iii, b-ii, c-i, d-iv
a-i, b-ii, c-iv, d-iii
a-ii, b-i, c-iii, d-iv
Correct Answer
Detailed Explanation
Myosin is known as the thick filament in muscle contraction, while tropomyosin is involved in masking the active sites on actin filaments. Cardiac muscle is striated and involuntary, and smooth muscle is also involuntary, which aligns with the correct pairings in option A.
