Myosin head (high-energy configuration) ADP Р Myosin head attaches to the actin myofilament, forming a cross bridge. Thin filament ADP Thick filament ADP ATP hydrolysis Р As ATP is split into ADP and P, the myosin head is energized (cocked into the high-energy conformation), Inorganic phosphate (P) generated in the previous contraction cycle is released, initiating the power (working) stroke. The myosin head pivots and bends as it pulls on the actin filament, sliding it toward the Milne. Then ADP is released. ATP . ATP -Myosin head (low-energy configuration) As new ATP attaches to the myosin head, the link between myosin and actin weakens, and the cross bridge detaches.
