Which of the following statements is FALSE? A) The resting potential of a cell develops because the cell membrane is more permeable to K⁺ than it is to most other ions. B) The concentration of Na⁺ is higher inside the cell than outside. C) Potassium ions only diffuse down their gradient until the charge difference across the membrane is great enough (electrical equilibrium) to prevent additional diffusion. D) Potassium's tendency to diffuse out is opposed by the attractive forces of the negative charge inside the cell. E) The sodium-potassium exchange pump maintains the normal resting concentrations of ions on either side of the cell membrane.

The concentration of Na+ is actually higher outside the cell than inside, which is a key aspect of the cell's electrochemical gradient and is maintained by the sodium-potassium pump.
