What is the role of tropomyosin in muscle contraction?

Tropomyosin blocks myosin binding sights on acting molecules.

Explanation:

It prevents cross-bridge formation, which also prevents 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.
