The role of energy with regard to the mechanism by which skeletal muscle cells contract. Introduction: Actin and myosin interact to promote muscle contraction and shortening. Myosin proteins associate in a parallel way with the extension of hinges and heads on the sides to form cross-bridges. Cross-bridge cycle during muscle contraction involves the following sequence of events: Binding of a cross-bridge to a thin filament. Movement of cross-bridge towards the H zone of the sarcomere. Detachment of the cross-bridge from the actin filament. Movement of cross-bridge away from the H zone for the cycle to begin again.
