Many amino acids in our diet are absorbed via the transcellular transport pathway by the intestinal epithelial cells.
This process requires ATP hydrolysis by ...
a) the Na+-amino acid symporter in the apical domain of the plasma membrane.
b) the Na+-amino acid antiporter in the apical domain of the plasma membrane.
c) the Na+-K+ pumps in the basolateral plasma membrane.
d) an amino acid carrier in the basal domain of the plasma membrane.
e) F-type ATPases in the apical domain of the plasma membrane.
