B) -70 millivolts
C) 50 millivolts
D) 100 millivolts

Question

Quizplus · Accepted Answer

The resting potential of a neuron is typically around -70 millivolts. This means that the inside of the neuron is negative relative to the outside. This resting potential is maintained by the sodium-potassium pump, which pumps three sodium ions out of the neuron for every two potassium ions that it pumps in, resulting in more positively charged ions being outside the neuron and more negatively charged ions being inside.
