WebMay 7, 2024 · The thin actin filaments also have binding sites for the myosin heads—a cross-bridge forms when a myosin head binds with an actin filament. The process of cross-bridge cycling is shown in Figure \(\PageIndex{6}\). A cross-bridge cycle begins when the myosin head binds to an actin filament. ADP and P i are also bound to the myosin head at … WebThick and thin filaments, which comprise the myofilaments, are composed primarily of the proteins myosin and actin, respectively, and the light band of the sarcomere is the portion where only thin filaments are present and the dark band is where both thick and thin filaments are present.
