Vedclass · Answer

(D) During the depolarization phase of a nerve impulse,the membrane potential becomes positive inside due to the rapid influx of $Na^+$ ions.However,the question asks what maintains the depolarized state or the ionic balance during the action potential cycle.Actually,the influx of $Na^+$ causes depolarization,while the efflux of $K^+$ ions is responsible for repolarization.In the context of standard multiple-choice questions regarding nerve impulse conduction,the movement of $K^+$ ions is the primary factor regulating the membrane potential after the initial spike.Thus,the correct option is $D$.
