Which of the following statements are correct regarding Na^ - K^+ pump? i) Needs energy (ATP) to work ii) Expels 3 Na^+ for every 2K^+ ions imported iii) Works against a concentration gradient iv) Maintains resting potential

Assertion : When a neuron is not conducting any impulse, i.e. resting, the axoplasm inside the axon contains high concentration of K^(+) and negatively charged proteins and low concentration of Na^(+) . Reason : In resting, the axonal membrane is comparatively more permeable to K^(+) ions and nearly impermeable to Na^(+) ions. Similarly, the membrane is impermeable to negatively charged proteins present in axoplasm
