NEET Zoology Muscle Contraction Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Motor neuron | (i) Involuntary muscle |
| (b) Troponin | (ii) Thin filament |
| (c) Cardiac muscle | (iii) Neuromuscular junction |
| (d) Actin | (iv) Calcium binding |
a-iii, b-ii, c-i, d-iv
a-ii, b-iv, c-iii, d-i
a-iv, b-i, c-ii, d-iii
a-i, b-iii, c-iv, d-ii
Correct Answer
Detailed Explanation
Motor neurons are involved in the neuromuscular junction, where they connect to muscle fibers. Troponin is a protein that binds calcium and is found on thin filaments (actin). Cardiac muscle is involuntary and striated, while actin is indeed a component of the thin filaments.
