Which is NOT a transport mechanism typically seen in renal tubular epithelial cells?
A. cotransport proteins in the luminal membrane of the proximal tubule that move Na+ and glucose from the proximal tubule into epithelial cells

C. ion channels that allow Na+ to move by diffusion from the lumen of the proximal tubule into epithelial cells
D. 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
E. countertransport proteins that move Na+ into proximal tubule epithelial cells while moving H+ from the cells into the lumen
