Animal cells have a membrane that separates the interior of the cell from the outside environment Typically an electric potential difference exists between the inner and outer surfaces of the membrane Consider one such cell where the magnitude of the potential difference is 53 mV and the outer surface of the membrane is at a higher potential than the inner surface A potassium ion K is initially just inside the cell membrane initially at rest How much work in 3 is required for a cell to eject the ion so that it moves from the interior of the cell to the exterior
