Step One AP - (MEP) -Na+ open channels = depolarization of membrane
Step Two Ca++ releases in SR
Step Three Myosin ATPase = ATP--> (ADP + Pi)
                                          myosin head



(REQUIRES ATP)
Step Four Calcium binds with troponin--->tropomyosin to move undercover binding sites (actin)

Step Five Myosin attaches
Step Six (ADP + Pi)  is released and head flexes 

-this is the ratchet effect
Step Seven ATP to myosin head for release



(REQUIRES ATP)
Step Eight Calcium reuptake into SR

(active transport)



REQUIRES ATP

Step Nine repolarization of membrane 

(active transport --> Na+/K+ pump)


REQUIRES ATP
How many times is ATP required? Four times

In steps: 3,7,8, & 9
