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 HPO4^2-

This will also be shown when we show the phosphate transport in a subsequent post
