WebWhen a cell achieves equilibrium between the concentration gradient and the (opposite) electrical gradient for a particular ion, the cell is then at its ‘equilibrium’ (=’E’). 2. In the … WebThe inside of the cell has a low concentration of sodium ions, and the outside of the cell has a higher concentration of sodium ions. Each sodium ion is counterbalanced by an anion that is found on the same side of the membrane as the sodium ion. The signaling cascade causes the ion channel to open, allowing cations to flow … And it uses ATP to do this.
