What is the next step in muscle contraction after the actin changes shape?
A. Myosin binds to actin.
B. A calcium ion binds to actin.
C. Myosin and actin slide past each other.
D. An ATP molecule binds to the myosin.

Answer :

The next step in muscle contraction after the actin changes shape is  Myosin binds to actin.

How do actin and myosin work?

The bridging filaments present and present high electronics, establishing stable bonds, which is called cross. Both filaments are arranged in such a way that the thin ones can slide over the thick ones, shortening the myofibrils, which leads to the contraction of the cells.

Thus, after the contraction of a muscle, actin slides over myosin in muscle cells, allowing the body to move.
