Which of the following statements concerning resting membrane potential is true? A) The resting plasma membrane is more permeable to Na⁺ than K⁺. B) The resting membrane potential never reaches an equilibrium point. C) The resting membrane potential is proportional to the tendency for K⁺ to diffuse out of the cell. D) Negatively charged Cl⁻ ions are attracted by negative charges in the cell. E) The purpose of the sodium-potassium pump is to create an equilibrium of ion concentrations.

Question

The resting membrane potential is largely determined by the potassium (K+) concentration gradient across the cell membrane, and the cell's permeability to K+. This gradient causes K+ to diffuse out of the cell, making the inside of the cell negatively charged relative to the outside, thus establishing the resting membrane potential.
