    1. Explain why the coupling of the import of amino acids or sugars into cells is typically linked to Na+ ion import.

    The Na+ concentration gradient across the cell membrane allows the sodium ions to flow into the cell, down their concentration gradient. Some sugars and amino acids use the above gradient to be transported into the cell along with the sodium ions. The sugar and amino acid transporters do not use ATP directly, but ...
