D) It pumps two K? out and allows two NA? in.

Question

Quizplus · Accepted Answer

The sodium-potassium pump maintains the resting potential of a neuron by pumping three sodium (Na⁺) ions out of the neuron and two potassium (K⁺) ions into the neuron, using ATP for energy. This creates a net loss of positive charge from the neuron, contributing to the negative resting membrane potential.
