ELECTROCHEMICALGRADIENT It is the potential of a ion that can moveacross the membraneIt has 2 parts that are iChemical Gradientwhere there is difference in solute concentrations andiiElectrical Gradient where there is difference in charges acrossa membraneFORCES THATDETERMINE SODIUM MOVEMENTThe sodium concentration is higher outside the cell because thesodium increase the negativity inside the cellAlthough the concentration of sodium higher outside the cellthe Cell do not allow the sodium to enter into cell at restThe Chemical Forces acting On Sodium do not allow to enter thecellThe Electrical forces acting on sodium allow the sodium toenter the cell when there is decrease in negativity inside the cellas
