What is primarily responsible for the development of a resting membrane potential?
A)More diffusion and active transport of cations out of the cell than into the cell
B)Pumping 2 K+ ions out of the cell for every three Na+ ions pumped into the cell
C)More K+ ions diffusing into the cell than there are Na+ ions diffusing out of the cell
D)More anions diffusing into the cell than are diffusing out of the cell
E)None of the above are primarily responsible.

Question

Quizplus · Accepted Answer

More K+ ions diffusing into the cell than there are Na+ ions diffusing out of the cell creates a net negative charge inside the cell, which repels further entry of anions and attracts cations, leading to the development of a resting membrane potential.
