Across the cell membrane of a skeletal muscle cell in the resting state with a non electrogenic pump (1 Na+ : 1K+)
Both sodium and potassium are in electrochemi¬cal equilibrium The rate of sodium influx is equal to the rate of potassium efflux The rate of sodium influx is much less than the rate of potassium efflux The rate of sodium influx is much greater than the rate of potassium efflux
