The sodium-potassium pump generates the following concentration gradients across the plasma membrane:

Question

Quizplus · Accepted Answer

The sodium-potassium pump is responsible for actively transporting three sodium ions out of the cell and two potassium ions into the cell, creating a concentration gradient where the concentration of sodium is higher outside the cell and the concentration of potassium is higher inside the cell. Therefore, the correct answer is C: low [Na+] and high [K+] inside the cell and high [Na+] and low [K+] outside.
