A. PCT, B. DCT, C. Collecting duct, D. All of the above
A: PCT
Answer: A: PCT 
Explanation: Ans. A: PCTGlucose, amino acids, and bicarbonate are reabsorbed along with Na+ in the early poion of the proximal tubule. Faher along the tubule, Na+ is reabsorbed with Cl-. Glucose is typical of substances removed from the urine by secondary active transpo. It is filtered at a rate of approximately 100 mg/ min (80 mg/ dL of plasma x 125 mL/ min). Essentially all of the glucose is reabsorbed, and no more than a few milligrams appear in the urine per 24 hours.
