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.
During contraction of a muscle, calcium ions bind to... the actin myofilament. the troponin molecule. the tropomyosin molecule. the sarcoplasmic reticulum. the sarcolemma. 2. The bond between the actin and myosin head is broken when... an ATP molecule binds to the myosin head.an ATP molecule binds to the actin molecule. an ATP molecule breaks down on the myosin head.he bond between the actin and myosin head is broken when... an ATP molecule binds to the myosin head. an ATP molecule binds to the actin molecule. an ATP molecule breaks down on the myosin head.
