The differences in concentration of which pair of ions produces the resting membrane potential? ​
A)sodium and potassium
B)sodium and chloride

D)chloride and calcium
E)calcium and sodium

Quizplus · Accepted Answer

The resting membrane potential is mainly determined by the concentration gradients of sodium and potassium ions across the cell membrane. The concentration of sodium ions is higher outside the cell, while the concentration of potassium ions is higher inside the cell. These concentration gradients generate a potential difference across the cell membrane, which contributes to the resting membrane potential. Therefore, choice A is correct.
