WebUnderstanding: • Calcium ions and the proteins tropomyosin and troponin control muscle contractions. The process of muscular contraction occurs over a number of key steps, including: Depolarisation and calcium ion release. Actin and myosin cross-bridge formation. Sliding mechanism of actin and myosin filaments.
