Question

Quizplus · Accepted Answer

The movement of molecules across the apical surface of epithelial cells by secondary transporters is often coupled to the sodium (Na+) gradient, which is maintained by the sodium-potassium (Na+/K+) pump located on the basolateral surface of the cell. This pump actively transports Na+ out of the cell and K+ into the cell, creating a concentration gradient that drives the secondary transport processes.
