B. sodium leaks out of the cell and potassium leaks into the cell

C. the inactivation gates on voltage-gated sodium channels are closed

D. the sodium-potassium pump moves sodium ions out of the cell and potassium ions into the cell

E. some sodium enters the cell, but no potassium leaves the cell

A. there are no open channels in the membrane

B. sodium leaks out of the cell and potassium leaks into the cell
