WebMembrane Potentials. In the cell, we use exactly the same principles as the two-chamber model, except that we initially use energy or work to separate the ions from each other. This energy comes in the form of the Na-K ATPase pump. This pump moves three Na+ ions out of the cell and two K+ ions into the cell (see figure below), using ATP (energy ... WebFor a cell’s membrane potential, the reference point is the outside of the cell.
