[{'content': 'Repolarization of nerve action potential is due to: \nSelect and explain. \nA. Inward sodium current, B. Inward potassium current, C. Inward potassium current and outward sodium current, D. Outward potassium current and inward sodium current', 'role': 'user'}, {'content': 'Answer: D \nExplanation: 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.', 'role': 'assistant'}]
