An ion that is essential for muscle contraction is Ca2+. Which of the following statements about the calcium ion and muscle contractions is TRUE? Select one: a. Muscle contractions can occur whether Ca2+ concentrations are high or low. b. Ca2+ binds to the tropin-tropomyosin protein complex shifting it out of the way and allows the myosin to bind to the actin so contraction can occur. c. When Ca2+ concentrations are high, tropomyosin inhibits myosin binding and the muscle is relaxed. d. Ca2+ ions are stored in the sacroplasmic reticulum during the muscle contractions. I do not know which one is
