What happens when a resting neuron's membrane depolarises?
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 is more negative than the outside.

Question

Quizplus · Accepted Answer

When a resting neuron's membrane depolarizes, the neuron's membrane voltage becomes more positive. This is due to an influx of positively charged ions, typically sodium ions, into the cell.
