Detailed explanation-1: -(1) Calcium binds to troponin C, causing the conformational shift in tropomyosin that reveals myosin-binding sites on actin. (2) ATP then binds to myosin.
Detailed explanation-2: -Calcium and adenosine triphosphate (ATP) has a crucial significance in powering or forcing muscle contraction activity. The contraction cycle of the muscles is induced by the calcium ions that significantly attach to a specialized protein complex, troponin, and thereby free the active-binding regions of the actin.
Detailed explanation-3: -The energy is derived from adenosine triphosphate (ATP) present in muscles. Muscles tend to contain only limited quantities of ATP. When depleted, ATP needs to be resynthesized from other sources, namely creatine phosphate (CP) and muscle glycogen.
