Explanation:
Exp. A
Troponin is a muscle protein that is involved in muscle contraction. Troponin is a complex of three proteins that are found in muscle cells.
- These protein are troponin \(\mathrm{C}\), troponin I, and troponin T. Troponin \(\mathrm{C}\) binds to calcium ion which are needed for muscle contraction, Troponin I prevents muscle contraction when there are no calcium ion present and troponin \(\mathrm{T}\) binds to tropomysin, which is a protein that covers the active sites of actin.
