Which of the following ions has the greatest influence on the resting membrane potential?
A) Sodium
B) Chloride
C) Calcium
D) Phosphate
E) Potassium

Question

Quizplus · Accepted Answer

Potassium ions have the greatest influence on the resting membrane potential due to the high concentration of intracellular potassium ions and the membrane's high permeability to potassium. This results in a negative resting potential as potassium ions flow out of the cell. The other ions listed, such as sodium and calcium, have a lesser effect on the resting potential.
