Question

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.

Explanation / Answer

The glucose in our diet is absorbed by via transcellular transport pathway by the intestinal epithelial cell . This process require ATP hydrolysis by the Na+ - K+ pumps in the basolateral plasma membrane.

Correct opption is C
