Which of the following is true?
A)The resting plasma membrane is more permeable to Na+ than K+.
B)The resting membrane potential never reaches an equilibrium point.
C)The resting membrane potential is proportional to the tendency for K+ to diffuse out of the cell.
D)Negatively charged Cl- ions are attracted by negative charges in the cell.
E)The purpose of the sodium-potassium exchange pump is to create an equilibrium of ion concentrations.

Question

Quizplus · Accepted Answer

The resting membrane potential is established by the unequal distribution of ions across the plasma membrane, with K+ being more concentrated inside the cell and Na+ more concentrated outside. The resting membrane potential is proportional to the tendency for K+ to diffuse out of the cell due to the concentration gradient, with the membrane potential becoming more negative as K+ leaves the cell.
