What is the role of tropomyosin in muscle contraction?

Answer:The role of tropomyosin in muscle contraction is that it blocks myosin binding sites on acting molecules. Tropomyosin is a protein in the muscle contraction and prevents myosin from grabbing it, this prevents muscle contraction. When the nervous system contracts, calcium is released.

Tropomyosin blocks myosin binding sights on acting molecules.

Explanation:

It prevents cross-bridge formation, which also prevents muscle contraction
