What two factors contribute to the negative resting potential of a neuron?
A) diffusion and electrostatic pressure
B) concentration gradient and ion channels
C) selective permeability and sodium-potassium pump
D) hyperpolarization and depolarization

Question

Quizplus · Accepted Answer

The negative resting potential of a neuron is maintained by the selective permeability of the cell membrane, which allows some ions to pass through while restricting others. The sodium-potassium pump also contributes to the negative resting potential by actively transporting 3 sodium ions out and 2 potassium ions in, against their concentration gradients.
