Question

During repolarization, what ions are pumped out of the cell?
A) sodium
B) potassium
C) both sodium and potassium
D) calcium

Accepted Answer

During repolarization, potassium ions are pumped out of the cell. This results in the restoration of the negative charge inside the cell and the positive charge outside, which is necessary for the cell to prepare for another action potential.
