<prompt> All of the following electrolytes are absorbed in distal convoluted tubule DCT, EXCEPT:NaKCa2Cl-  <response>: Only about 10 of the filtered NaCl is reabsorbed in the distal convoluted tubule DCT. Like the TAL of Henles loop, this segment is relatively impermeable to water, and NaCl reabsorption fuher dilutes the tubular fluid. The mechanism of NaCl transpo in the DCT is an electrically neutral thiazide-sensitive Na and Cl- cotranspoer. Because K does not recycle across the apical membrane of the DCT as it does in the TAL, there is no lumen-positive potential in this segment. Ca2 is actively reabsorbed by the DCT epithelial cell an apical Ca2 channel and basolateral NaCa2 exchanger. This process is regulated by parathyroid hormone. Ref: Eaton D.C., Pooler J.P. 2009.
