Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Glucose is reabsorbed from the tubule epithelial cells into the capillaries surrounding the proximal convulated tubule by..
A
diffusion and active transport
B
facilitated diffusion and active transport
C
osmosis and active transport
D
facilitated diffusion and passive transport
Explanation: 

Detailed explanation-1: -The glucose molecule then diffuses across the basal membrane by facilitated diffusion into the interstitial space and from there into peritubular capillaries. Most of the Ca++, Na+, glucose, and amino acids must be reabsorbed by the nephron to maintain homeostatic plasma concentrations.

Detailed explanation-2: -1. Glucose transport in the kidney. Under normoglycemia, ∼97% of filtered glucose is reabsorbed via the Na+-glucose cotransporter SGLT2 primarily in the early segments of the proximal tubule.

Detailed explanation-3: -Sodium/proton exchanger, which enables reabsorption of bicarbonate. Glucose, amino acids and other substances diffuse out of the epithelial cell down their concentration gradients on passive transporters and are then reabsorbed by the blood capillaries.
