The resting potential of a typical nerve cell membrane is determined primarily by a transmembrane equilibrium dominated by its permeability to:

Question

Quizplus · Accepted Answer

The resting potential of a nerve cell membrane is largely determined by the differential permeability of the membrane to various ions, particularly potassium ions (K+). Because the membrane is more permeable to K+ than to any other ion, the resting potential is closer to the equilibrium potential for K+ than to that for any other ion. Therefore, the correct answer is (B) K+.
