The channels that allow sodium to flow into the neuron close and the channels that allow potassium to flow out open.Which statement about the state of the neuron is accurate?
A)It has reached its action potential threshold.
B)It is in the process of being depolarized and will soon fire.
C)It is in the process of returning to its original resting state.
D)It has an ion exchange malfunction.

Question

Quizplus · Accepted Answer

The given statement describes the process of repolarization, during which the neuron returns to its original resting state after firing an action potential. Option A states that the neuron has reached its action potential threshold, which is incorrect as the statement describes the repolarization phase after surpassing the threshold. Option B suggests that the neuron is in the process of depolarization and about to fire, which is the opposite of what is described in the statement. Option D implies that there is a malfunction in the ion channels, which is unsupported by the given information.
