Some cells in the body can maintain an electric potential across their cell membrane. How do they do this?

  1. By using the sodium-potassium pump to continually eject positive sodium and potassium ions from the cell.
  2. By allowing negative chloride ions to enter the cell along their concentration gradient.
  3. By trapping large cations inside the cell membrane.
  4. By keeping unequal concentrations of various ions on each side of the cell membrane.
