Suppose a neuron has a “gap” in its axon-a region with no voltage-gated Na^or K^channels. Which statement below is TRUE? The action potential can move past this region as long as the neuron adds K^+ channels to the gap. The action potential can move past this region as long as the depolarization at one end spreads far enough to open sufficient Na^+ channels at the other end. There is no way that an action potential can move past such a gap because Na^+ channels must be right next to each other to sense changes in V_m. The action potential can depolarize the whole length of the axon: however, the lack of K^+ channels in the gap would result in the neuron returning to its resting potential very slowly.
