Question
Solution 1
Phase C of the action potential, also known as the repolarization phase, is characterized by the efflux (outflow) of potassium ions (K+). This happens due to the opening of voltage-gated potassium channels and the closing of sodium channels that were open during the depolarization phase (Phase B).
