Which is NOT a transport mechanism typically seen in renal tubular epithelial cells?
A. Transport proteins that move glucose by facilitated diffusion from inside of proximal tubule cells into the renal interstitial fluid
B. Na+-K+ ATPase pumps in the luminal membrane of proximal tubule epithelial cells that move Na+ from inside the cell into the tubule and K+ from the tubule lumen into the cell
C. Countertransport proteins that move Na+ into proximal tubule epithelial cells while moving H+ from the cells into the lumen
D. Ion channels that allow Na+ to move by diffusion from the lumen of the proximal tubule into epithelial cells
E. Cotransport proteins in the luminal membrane of the proximal tubule that move Na+ and glucose from the proximal tubule into epithelial cells
