Which of the following statements correctly describe the compartmentalization and roles of Sodium () — s Block Elements Chemistry Question

💡 Solution & Explanation

$Na^+$ is extracellular, while $K^+$ is intracellular and activates glucose-oxidizing enzymes. The drastic concentration differences across the membrane generate electrical nerve impulses. Statement C is incorrect because these gradients are actively maintained against equilibrium by the ATP-consuming $Na^+/K^+$ pump.
