Calcium is important in skeletal muscle contraction because itA. detaches the myosin head from the actin filamentB. activates the myosin ATPase by binding to itC. binds to troponin to remove the masking of active sites on actin for myosinD. prevents the formation of bonds between the myosin cross bridges and the actin fiiament

Answer» Correct Answer - C
Calcium plays a key regulatory role in muscle contraction. `Ca^(2+)` ions bind to troponin and changes its shape and position. This in turn, alter the shape and position of tropomyosin and hence, the active sites on F-actin are exposed. Due to this, myosin cross-bridges are able to bind to these active sites and muscle contraction occurs
