E)None of these choices

Question

Quizplus · Accepted Answer

The resting membrane potential in neurons typically ranges from -40 to -90 mV. This is due to the large concentration gradient of ions across the cell membrane, specifically the higher concentration of potassium ions inside the cell compared to outside and the higher concentration of sodium ions outside the cell compared to inside. The negatively charged proteins inside the cell also contribute to the negative resting membrane potential.
