If all of the Ca²⁺ within a muscle fiber was removed, which of the following could still occur? A) The heads of the myosin myofilaments would bind to G-actin to form cross-bridges. B) An action potential that was produced at the neuromuscular junction would be propagated along the sarcolemma. C) The troponin molecules bound to G actin molecules would be released, causing tropomyosin to move. D) The heads of the myosin molecules would return to their resting position, and the recovery stroke would occur.
