The correct answer is: The high concentration of glucose saturates the reabsorption pumps, causing glucose to appear in the urine.
Diabetes mellitus is a condition wherein there is an excess of glucose produced in the body due to the ineffective functioning of the pancreas. The diabetic patients often have glucosuria (glucose in the urine) due to the malfunctioning of the renal tubules to reabsorb all the filtered glucose back into the blood.
