The equilibrium potential for an ion species may be defined asthat potential required to keep the ions at a given concentrationand may be calculated from the nernst equation for that ionspecies. The concentration of K+ inside a squid axon is 400 mM andthe external concentration is 10 mM. The equilibrium […]
