How many questions need to be on your final at least? How many documents will you submit? What will you do for the multiple choice answers in the answer key?

It binds to calcium and tropomyosin. When calcium binds to troponin in moves tropomyosin to allow contraction to take place
What is the importance of ATP in muscle contraction?
Gets broken down to move myosin to the high energy state. Binds to myosin to break crossbridge.
What is the Frank Starling Mechanism?
The more a ventricle fills, the more force it exerts to pump blood.
