<prompt> Which of the following is NOT true statement about ions in extra and intracellular compaments?Cl- is the main anion in interstitial fluidNa is main cation in plasmaMg2 is second major cation present in intracellular fluid after KHC03- is mainly present in intracellular fluid  <response>: Extracellular fluid ECF is characterized by high Na and Ca2 content, and Cl- is the major anion. HCO3- is abundant in ECF. The intracellular fluid is rich in K and Mg2, and phosphate is its major inorganic anion. The cytosol of cells contains a high concentration of protein that acts as a major intracellular buffer. Ref: Murray R.K., Granner D.K. 2011. Chapter 40. Membranes: Structure Function. In D.A.
