The main ion responsible for the restoration of the resting potential is _____.
A) sodium
B) calcium
C) potassium
D) magnesium

Question

Quizplus · Accepted Answer

The main ion responsible for the restoration of the resting potential is potassium. During an action potential, potassium ions move out of the cell, leading to a temporary hyperpolarization. In order to restore the resting potential, potassium ions must move back into the cell. This movement is driven by the concentration gradient and voltage gradient established during the action potential. Therefore, potassium is the key ion responsible for restoring the resting potential.
