How is a neuron's resting potential restored after an action potential has passed a particular segment of the axon?
A) Sodium ions are pumped into the cell.
B) Chloride ions are pumped into the cell.
C) Sodium ions are pumped out of the cell.
D) Potassium ions are pumped out of the cell.

Question

Quizplus · Accepted Answer

After an action potential passes a particular segment of the axon, the cell restores its resting potential by pumping out potassium ions using ATP-dependent pumps. This process, known as repolarization, allows the neuron to return to its resting potential of around -70mV.
