Which of the following is not a role of ionic calcium in muscle contraction?

Question

Quizplus · Accepted Answer

Ionic calcium does not activate epinephrine released from the adrenal gland. Instead, epinephrine is released in response to stress and triggers the release of stored glycogen and the breakdown of fatty acids to provide energy for muscle contraction. The other three options are all roles of ionic calcium in muscle contraction. It removes the contraction inhibitor by binding to troponin which allows myosin to interact with actin and initiate contraction. It triggers neurotransmitter secretion from motor neurons which activates muscle contraction. It also promotes the breakdown of glycogen and ATP synthesis which provides energy for muscle contraction.
