Quizplus · Accepted Answer

Cross bridge formation involves the binding of myosin heads to actin filaments, which is triggered by the release of calcium ions from the sarcoplasmic reticulum and the hydrolysis of ATP to provide energy for the movement of the myosin heads. Therefore, both calcium ions and ATP are required for cross bridge formation.
