Detailed explanation-1: -Final answer: Glucose is completely reabsorbed in the kidneys.
Detailed explanation-2: -Glucose is reabsorbed in the renal tubule by.
Detailed explanation-3: -Glucose is actively reabsorbed in PCT along with other ions, whereas water is passively reabsorbed in PCT. Most of the filtered Glucose re-absorption occurs via the action of sodium-glucose ion transporter.
Detailed explanation-4: -Most of the glucose entering the tubular system is reabsorbed along the nephron segments, primarily in the proximal tubule, such that urine is almost free of glucose. This is different in diabetes, where the filtered glucose exceeds the transport capacity of the tubular system for glucose and glucosuria occurs.
Detailed explanation-5: -Tubular reabsorption of glucose is an important process that occurs in the kidneys to maintain normal blood glucose levels. When blood is filtered through the glomeruli in the kidneys, glucose is freely filtered into the tubular fluid of the nephron.
