Which of the following is incorrect regarding sodium and potassium ion

1.	Which of the following is incorrect regarding sodium and potassium ions?(a) Responsible for maintenance of extracellular and intracellular fluids(b) Responsible for transmission of electrical impulses(c) Responsible for the maintenance of membrane potential(d) Responsible for nitrogen fixation in animalsThis question was posed to me in unit test.Asked question is from Biomolecules in chapter Biomolecules of Biology – Class 11
Answer» Right choice is (d) Responsible for nitrogen fixation in animals The BEST EXPLANATION: Sodium and POTASSIUM are responsible for the maintenance of extracellular and intracellular fluids through the osmotic effects of the concentration of these TWO ions. These two ions are also responsible for the maintenance of membrane potential and the transmission of electrical impulses in the NERVE cells.
