Short Answer

Draw a cell that secretes bicarbonate into the lumen of the pancreas, selecting transporters and/or enzymes from the following list (you may or may not need them all):
chloride channel
CFTR channel
GLUT4
H⁺-K⁺-ATPase
Na⁺-Cl⁻-K⁺ Symport
Cl⁻ - HCO₃⁻ Antiport
Cl⁻ - HCO₃⁻ Symport
carbonic anhydrase
K⁺ leak channel
leaky junctions
Na⁺-K⁺-ATPase
Na⁺-H⁺ antiport
Label the cell showing the lumen, interstitial fluid, the basolateral membrane, and the apical membrane.
