Renal Tubular Transport #2. S1 Segment, Proximal Tubule. Sodium Transport 2 (Sodium/Phosphate Transport)
(Edited)
The same electrochemical gradient generated by the Na/K ATPase mentioned in the previous post serves as the force behind the sodium/phosphate cotransporter
Here, we show the following in the apical membrane of the S1 segment of the proximal tubule.
- The NaPi2 cotransporter, which brings 3 sodium ions with 2 HPO42-
This will also be shown when we show the phosphate transport in a subsequent post
