What would happen to a neuron's electrochemical gradient if the plasma membrane became strongly permeable to Na⁺?

Question

Quizplus · Accepted Answer

If the plasma membrane became strongly permeable to Na+ (sodium ions), Na+ would flow into the neuron, reducing the voltage difference across the membrane. Normally, the inside of a neuron is negatively charged relative to the outside; increased Na+ permeability would make the inside less negative, thus decreasing the voltage difference.
