A particular co-transporter uses the concentration gradient of Na+ to move an amino acid into the cell. What immediate effect would raising the extracellular Na+ have? It would…

A. increase the amino acid\'s rate of entry into the cell.

B. block the movement of the amino acid into the cell.

C. block the Na+ / K+ pump.

D. speed up the Na+ / K+ pump.

E. reverse the direction of the Na+ / K+ pump so that it moves Na+ and K+ down their concentration gradients.
