Thin myofilaments are primarily composed of myosin proteins.________ 17. An accumulation of lactic acid is the principal cause of sore muscles________ 18. Anaerobic respiration is the first choice of the muscle cell for the production of ATP. ________ 19. During rest, excess oxygen molecules in the sarcoplasm are attracted to a large protein molecule called myoglobin. ________ 20. To initiate muscle contraction, calcium ions bind to and change the shape of the troponin protein molecules, which then pull the tropomyosin proteins off the myosin binding sites of the actin helix.arrow_forward
