"Rank the sequence of cross bridge cycling, starting with the myosin-binding sites being exposed and ending with relaxation due to cross bridge cycling ending. Do not overlap any events."
Sequence:
a. Calcium ions pumped into the sarcoplasmic reticulum
b. Myosin head forms cross bridge with actin
c. Myosin binding sites covered
d. Power stroke moves thin filament
e. Cross bridges detach from actin
