The Sliding Filament Theory

The conformation change results in a “cocking” of the myosin head and prepares it for the next step. Step 3: Myosin head attaches to actin myofilament. At this point, the myosin head enters its high-energy configuration and binds to the actin myofilament. Before this step, the ADP and Pi are still bound to the myosin head. ................
