The sodium-potassium pump is called an electrogenic pump because it:
a. pumps equal quantities of Na and K across the membrane
b. pumps hydrogen ions out of the cell
c. contributes to the membrane potential
d. ionizes sodium and potassium atoms
e. is used to drive the transport of the other molecules against a concentration gradient

c. contributes to the membrane potential
"In order to maintain the cell potential, cells must keep a low concentration of sodium ions and high levels of potassium ions within the cell (intracellular)....via active transport thus maintaining cell volume..."- wikipedia
