True regarding RMP is all except 
Select and explain. 
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
D: Na+ - K+ pump 3K+ out of cell & 2 Na+ inside of cell
Answer: D: Na+ - K+ pump 3K+ out of cell & 2 Na+ inside of cell 
Explanation: 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)
