Tubular reabsorption of glucose
Reabsorption of glucose occurs in a two step process involving reabsorption across the luminal membrane via Na-glucose cotransporter and then facilitated glucose transport across the peritubular membrane. Under 200 mg/dL, all glucose filtered into Bowman’s space is reabsorbed. As plasma concentrations approach 350 mg/dL the glucose transporters become saturated and glucosuria can occur.
