If you experimentally increase the concentration of Na⁺ outside a cell while maintaining other ion concentrations as they were,what would happen to the cell's membrane potential?

Question

Quizplus · Accepted Answer

Increasing the concentration of Na⁺ outside the cell would increase the membrane potential because the electrochemical gradient for Na⁺ would become steeper, leading to a greater influx of Na⁺ into the cell, thus depolarizing the membrane.
