Repolarization of nerve action potential is due to:
Ans. D. Outward potassium current and inward sodium currentThe repolarization is due to the opening of voltage-gated K+ channels (K+ outward movement).During this Na+ channels rapidly enter a closed state called the inactivated state. So, few Na+ still enter during repolarization also.
