As an action potential reaches a muscle cell, it triggers calcium to release from the sarcoplasmic reticulum of the cells. The calcium ions then flow into the cytoplasm and bind to the troponin and tropomyosin molecules in the actin filaments of the muscle cells. The binding of calcium allows the troponin to change shape and expose the actin-myosin binding site.
Effects on Muscles. Calcium and magnesium play roles in muscle health. Magnesium helps muscles to release, while calcium helps them to contract. That is why it is so important to obtain a balance of the two minerals.
