A) Concentration of calcium ions in the cytosol is greatly reduced by active transport; Ca 2+-ATPase pumps
B) Concentration of calcium ions in the cytosol is greatly reduced by active transport; Ca 2+/Na+ cotransporters in sarcoplasmic reticulum and sarcolemma
C) The release of actin protein degrading enzymes
D) The release of myosin degrading enzymes
E) Both concentration of calcium ions in the cytosol is greatly reduced by active transport; Ca 2+-ATPase pumps and concentration of calcium ions in the cytosol is greatly reduced by active transport; Ca 2+/Na+ cotransporters in sarcoplasmic reticulum and sarcolemma are correct
