In a neuron at rest, there is a difference in the electrical charge across the cell membrane, with the inside of the cell being more negative than the outside.This is primarily due to A) leak currents produced by the permeability of the membrane to K⁺ ions. B) the difference in the concentrations of Na⁺ inside and outside of the cell. C) the difference in the concentrations of Cl^- inside and outside of the cell. D) leak currents produced by the diffusion of Ca²⁺ ions. E) the difference in concentrations of Ca²⁺ inside and outside of the cell.

The resting membrane potential is primarily due to leak currents produced by the permeability of the membrane to K⁺ ions, which allows K⁺ to diffuse out of the cell, making the inside more negative.
