1.	How many sodium ions are transported for every 2 potassium ions by the Na-K pump?(a) 2(b) 3(c) 1(d) 0This question was addressed to me during an interview.My doubt is from Neuron-1 topic in chapter Neural Control and Coordination of Biology – Class 11
Answer» Correct ANSWER is (B) 3 Best EXPLANATION: At resting membrane potential, to maintain the ionic gradient, 3 sodium IONS are transported out of the axonal membrane for EVERY 2 potassium ions moving into the cell, by the Na-K pump.
