[{'content': 'Which of the following is reabsorbed along with sodium in early poion of proximal tubules? \nSelect and explain. \nA. Glucose, B. Amino acids, C. Bicarbonate, D. All of the above', 'role': 'user'}, {'content': "Answer: D \nExplanation: Glucose, amino acids, and bicarbonate are reabsorbed along with Na+ in the early poion of the proximal tubule. Glucose is typical of substances removed from the urine by secondary active transpo. Also know: Normally about 60% of the filtered Na+ is reabsorbed in the proximal tubule, primarily by Na-H exchange. Another 30% is absorbed the Na-2Cl-K cotranspoer in the thick ascending limb of the loop of Henle. Ref: (2012). Chapter 37. Renal Function & Micturition.
