Which of the following is reabsorbed along with sodium in early poion of proximal tubules?
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.
