Calcium is important in skeletal muscle contraction
because it :-
(1) binds to troponin to remove the masking of
active sites on actin for myosin.
(2) activates the myosin ATPase by binding to it.
(3) detaches the myosin head from the actin
filament.
(4) prevents the formation of bonds between the
myosin cross bridges and the actin filament.
