<prompt> NaCl sympo is present in which pa of the nephron?PCTLoop of HenleDCTCollecting duct  <response>: In DCT: - The sympoer is NCC Na-Cl- cotranspoer In the PCT, the apical membrane has NaH-antipoer, which couples H secretion with the Na movement across the apical membrane. In the TAL of loop of Henle: - The sympoer NKCC moves 1 Na, 1 K, 2 Cl- through the apical membrane into the cell. In the late distal tubule and collecting duct: - Na diffuses across the apical membrane through the epithelial Na channel ENaC.
