Mechanism of muscle contraction quizlet

WebMolecular mechanisms of contraction The nerve impulse that ultimately results in muscle contraction appears as an action potential at the sarcolemma, the membrane that surrounds the muscle fibre. This electrical signal is communicated to the myofilaments inside the fibre in the following way. Webfor muscle contraction to happen, sufficient amounts of Ca2+ must bind to troponin. This happens when the Ca2+ concentration of the sarcoplasm rises above 10^-6 molar. …
