Reabsorption involves what two methods of transport? Describe each. What determines which route a solute will take?
What will be an ideal response?
1. transepithelial transport: substances cross both apical and basolateral membranes of the tubule epithelial cell.
2. paracellular pathway: substances pass through the junction between two adjacent cells.
The permeability of the epithelial junction and the electrochemical gradient for the solute determines which route it will take.
