NEET Zoology Muscle Contraction Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Motor Unit | (i) Calcium ions bind to troponin |
| (b) Sarcomere | (ii) Acetylcholine release |
| (c) Neuromuscular Junction | (iii) Functional unit of muscle contraction |
| (d) Myoglobin | (iv) Oxygen storage pigment |
a-ii, b-iii, c-i, d-iv
a-ii, b-i, c-iv, d-iii
a-i, b-iv, c-ii, d-iii
a-ii, b-iii, c-iv, d-i
Correct Answer
Detailed Explanation
A motor unit consists of a motor neuron and the muscle fibers it innervates (ii). A sarcomere is defined as the functional unit of muscle contraction (iii). The neuromuscular junction is where acetylcholine is released to initiate muscle contraction (i). Myoglobin serves as an oxygen storage pigment in muscle tissue (iv).
