The most crucial factor determining the resting potential of a neuron is the diffusion of
A) potassium out of the cell through leak channels.
B) potassium into the cell through gated channels.
C) sodium out of the cell through leak channels.
D) sodium into the cell through gated channels.

Question

Quizplus · Accepted Answer

The resting potential of a neuron is primarily determined by the diffusion of potassium ions out of the cell through leak channels, due to the high permeability of the membrane to potassium compared to other ions.
