An electrogenic Na+ transporter:

#Section 2: General Biology

  1. catalyzes facilitated diffusion of Na+ from a region of high Na+ concentration to one of lower Na+  concentration.

  2. must catalyze an electron transfer (oxidation-reduction) reaction simultaneously with Na+ transport.

  3. must transport both Na+ and a counterion (Cl–, for example).

  4. transports Na+ without concurrent transport of any other charged species.
