In diabetes mellitus the blood glucose level is high and appears in urine This due to a property of carrier proteins along kidney tubules namely?

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.
