The resting potential across the neuronal membrane is generally maintained by the
A) sodium-potassium pump.
B) action potential.
C) resting potential.
D) voltage-gated channels.
E) negative ion pump.

Question

Quizplus · Accepted Answer

The resting potential across the neuronal membrane is maintained by the sodium-potassium pump. This pump pumps out 3 sodium ions for every 2 potassium ions it pumps in, leading to a net loss of positive charge inside the cell and maintaining the negative resting potential.
