How is muscle contraction reversed? A. Calcium binds to calmodulin and is quickly degraded to relieve calcium’s inhibition of tropomyosin. B. Calcium is neutralized by an influx of negatively charged ions, which block calcium from binding to myosin. C. Calcium ion pumps in the sarcoplasmic reticulum reduce the cytosolic calcium levels and tropomyosin blocks the myosin-binding site on actin. D. Calcium is pumped out of the cell to reverse the voltage and cause myosin to degrade
