Transmembrane potential : the gradient of electrical energy across the plasma membrane of a cell (a potential difference). Resting membrane potential is the steady-state electrical condition of a cell. Resting membrane potential: 1) influences the transport of nutrients into and out of cells. 2) is a key driving force in the movement of salt (and therefore water) between tissue compartments. 3)
