1 Answer Option C The next phase after reaching the depolarisation phase of 30mV is the repolarization phase This phase events are characterized by returning of the action potential to the resting membrane potential So the events are opening of the voltagegated K channel with the closing of the voltagegated Na channel as the increase the membrane potential of positivity should be reduced by the removal of the K ions from the interior See Answer
