웹2024년 12월 19일 · The reabsorption in the proximal tubule is isosmotic. The proximal tubules reabsorb about 65% of water, sodium, potassium and chloride, 100% of glucose, 100% amino acids, and 85-90% of bicarbonate. This reabsorption occurs due to the presence of channels on the basolateral (facing the interstitium) and apical membranes (facing the tubular lumen). 웹Sodium also moves into enterocytes via sodium/hydrogen exchangers 3 (NHE3, SLC9A3, on luminal side) and 2 (NHE2, SLC9A2, on basolateral side), which shuttle sodium into enterocytes in exchange for a proton. Several in the basolateral membrane also mediate sodium influx. Important examples are the sodium/bicarbonate cotransporter (NBC1, …
