Which of the following is true for the epithelial cells of the kidney proximal tubule?
A. The sodium-glucose co-transporter in the luminal membrane is responsible for the net flux of glucose from intracellular space to the luminal space in the lumen of the proximal tubule.
B. The sodium-potassium pump in the basolateral membrane is responsible for the net flux of sodium from interstitial space to intracellular space.
C. The GLUT2 transporter in the basolateral membrane is responsible for the net flux of glucose from intracellular space to interstitial space.
