Detailed explanation-1: -They work by inhibiting SGLT2 transporters in the PCT. This prevents sodium and glucose reuptake, which has two main effects. Firstly, glucose cannot be reabsorbed and is thus excreted, reducing blood-glucose levels.
Detailed explanation-2: -Urea is passively reabsorbed in the proximal tubule, but its route of transport is not clear. Urea transporters have not yet been identified for the proximal tubule. SGLT1 can transport urea via Na–urea transport.
Detailed explanation-3: -About 67 percent of the water, Na+, and K+ entering the nephron is reabsorbed in the PCT and returned to the circulation. Almost 100 percent of glucose, amino acids, and other organic substances such as vitamins are normally recovered here.
Detailed explanation-4: -Answer and Explanation: The answer is B) Creatinine. Creatinine is considered a waste product, which is why it would not be reabsorbed; it would be secreted and then excreted from the body via urine.
