Calcium ions are necessary to activate the binding sites on the actin filaments. The ATP molecule is required each time the myosin head detaches from one side and re-attaches to another.
<h3>What do you mean by actin filaments?</h3>
It is microfilaments that are responsible for cell shape and cellular movements.
The calcium ions are released when there is depolarization of the sarcomere occurs. They then bind to troponin and restructure the complex that is exposing the binding sites to the myosin head.
The cellular importance of the motor proteins is ATP-dependent which forces the impulse to actin filaments, and then the myosin head detaches from the old binding sites of actin.
Therefore, Calcium ions are necessary to activate the binding sites on the actin filaments. The ATP molecule is required each time the myosin head detaches from one side and re-attaches to another.
