Differences in ion concentrations inside and outside a cell cause a difference in the charge of the intracellular and extracellular environments. This electrical polarization of a cell relative to its environment is referred to as cellular membrane potential. This potential serves as an energy source for a variety of cellular functions and as a way for excit ... Show More
