Question

Calcium plays a crucial role in skeletal muscle contraction by binding with troponin to remove contraction inhibition. This enables the myosin heads to bind with the actin filaments and generate force. Calcium is released from the sarcoplasmic reticulum in response to an action potential, allowing for muscle contraction to occur.
