Question

Quizplus · Accepted Answer

The concentration of glucose in tubular epithelial cells is maintained in an elevated state by sodium-linked secondary active transporters on the apical membrane. These transporters use the sodium gradient to drive the uptake of glucose against its concentration gradient, a process known as secondary active transport.
