Figure 6. Predicted fluxes across paracellular and transcellular pathways in the absence of inhibitors .

Predicted fluxes (pmol min^–1 mm^–1) under asymmetric conditions, at the CCD inlet (A) and outlet (B). Not shown are basolateral Na⁺/H⁺ exchangers, basolateral 2Na⁺‐HPO₄ ²⁻ cotransporters and apical H⁺/K⁺‐ATPase type 1 pumps.
