Tropomyosin Troponin Actin 600000000 Myosin Myosin filament Image from Sigma-Aldrich 
Myosin head (high-energy configuration) ADP P Myosin head attaches to the actin myofilament, forming a cross bridge. Thin filament ADP ATP 'hydrolysis ADP Thick filament 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 line. 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.
