What happens when a resting neuron's membrane depolarizes?
A) There is a net diffusion of Na+ out of the cell.
B) The equilibrium potential for K+(Ek) becomes more positive.
C) The neuron's membrane voltage becomes more positive.
D) The cell's inside becomes more negative than the outside.

Question

Quizplus · Accepted Answer

Depolarization of a neuron's membrane means that the membrane potential becomes less negative, moving towards zero or becoming positive. This is typically due to the influx of positively charged ions like Na+ into the cell, making the inside of the neuron more positive relative to the outside.
