Question

Which of the following transporters is NOT found embedded in the membrane of the intercalated cells of the late distal tubule and collecting ducts?

1) HCO₃-/Cl⁻ countertransporters in the basolateral membrane
2) Na⁺/HCO₃- cotransporters in the basolateral membrane
3) chloride channels in the basolateral membrane
4) H+ pumps in the apical membrane
5) K⁺/H+ countertransporters in the apical membrane

Answer 1

The transporter that is not found in the membrane of the intercalated cells of the late distal tubule and collecting ducts is the K⁺/H⁺ countertransporters in the apical membrane.

Step-by-step explanation:

The transporter that is NOT found embedded in the membrane of the intercalated cells of the late distal tubule and collecting ducts is the K⁺/H⁺ countertransporters in the apical membrane.
