Understanding Glucose in Urine: The Role of Glucose Transporters in Diabetes

The correct answer is: glucose transporters

Glucose transporters are proteins that facilitate the movement of glucose across cell membranes. In the kidney, glucose transporters are located in the proximal tubules, where they reabsorb glucose from the glomerular filtrate back into the bloodstream. In diabetes mellitus, the reabsorption of glucose is impaired, leading to the appearance of glucose in the urine.
