Which is true of a neuron with a resting potential?
A) The cell membrane is permeable to Na+ but impermeable to K+ ions.
B) The outer surface of the plasma membrane has a negative charge.
C) The highest concentration of K+ is extracellular.
D) The sodium pump has moved Na+ to the outside of the plasma membrane.

Question

Quizplus · Accepted Answer

The sodium-potassium pump actively transports Na+ ions out of the neuron and K+ ions into the neuron, maintaining the resting potential by keeping a higher concentration of Na+ outside the cell.
