Muscle contraction:
- The activation of tightening the muscle cells results in muscular contraction.
- Muscle contractions are caused by calcium ions.
- The sarcoplasmic reticulum releases calcium ions in response to the action potential,
- It binds to troponin on the actin filaments and causes conformational changes that expose the myosin-binding sites.
