ATP Hydrolysis/ Formation of cross Bridges/ Power Stroke/ Detachment of myosin from Actin
List the four steps of the contraction cycle (In order)
sliding filament mechanism
myosin heads attach to and walk along thin filaments at both ends of a sarcomere
the onset of contraction begins with the SR releasing calcium ions into the muscle cell, where they bind to actin opening the myosin binding sites
detachment of myosin from actin
step when as the next ATP binds to the myosin head, the hyosin head detaches from actin
