Question

Quizplus · Accepted Answer

The resting membrane potential is primarily generated by the permeability of the plasma membrane to potassium ions (K+). This is because the membrane is more permeable to K+ than to other ions, and the movement of K+ out of the cell (due to concentration gradients) is the main determinant of the negative charge inside the cell relative to the outside.
