Whether defective ENaC channel proteins are increasing or decreasing the apical Na + movement, connecting it with characteristics of hypokalemia. Introduction: Different ion channels in the body help in the passage of ions through a membrane. They are activated when the concentration of the ions across the membrane changes due to change in the membrane potential.
