All of the following help to maintain a neuron's resting potential except:
A) sodium-potassium pump activity.
B) sodium ions building up inside the neuron.
C) closed channels for sodium.
D) closed channels for potassium.

Question

Quizplus · Accepted Answer

Sodium ions building up inside the neuron would actually shift the membrane potential away from the resting potential, making it more positive. The other choices (sodium-potassium pump activity, closed channels for sodium, and closed channels for potassium) all contribute to maintaining the resting potential.
