True regarding RMP is all except: (A) -70 mV in neurons, (B) Is due to K+ ions, (C) Na+ - K+pump 3 Na+out of cell & 2K+ inside, (D) Na+ - K+ pump 3K+ out of cell & 2 Na+ inside of cell
Answer is D. RMP of nerve Fibre is - 70mV. Na+K+ATPase pump out 3Na+ in exchange for only 2K+. (REF: DISEASES GANONG'S REVIEW OF MEDICAL PHYSIOLOGY)
