The relative refractory period of an axon coincides with the period of A) activation and inactivation of voltage-dependent Na⁺ channels. B) Na⁺ permeability that is greater than that during the depolarization phase. C) increased K⁺ flux into the cell. D) increased K⁺ permeability of the cell. E) Increased Na⁺ flux through K⁺ channels.

Question

Quizplus · Accepted Answer

During the relative refractory period, the axon experiences increased K⁺ permeability, which makes it more difficult to initiate another action potential.

The Relative Refractory Period of an Axon Coincides with the Period
