Question

chii chinonzi tropomyosin mumabhonzo emabhonzo?

Answer 1

Answer:

Tropomyosin is a protein involved in skeletal muscle contraction and that wraps around actin and prevents myosin from grabbing it. ... When the nervous system tells the muscle cell to contract, calcium is released. The calcium activates the troponin complex, which moves tropomyosin, and the muscle cell can contract.
