Q. The function of $Na^{+}$ and $K^{+}$ pump is to move
A) $Na^{+}$ in and $K^{+}$ out
B) $Na^{+}$ out and $K^{+}$ in
C) $Na^{+}$ out and ${Cl}^{-}$ in
D) ${Cl}^{-}$ out and $Na^{+}$ in
Explanation
The process of expelling out sodium ions and drawing in potassium ions against concentration and electrochemical gradients is termed as sodium potassium pump. It occurs normally to maintain the normal difference in the ionic concentrations and electric potential between the outside and inside of the plasma membrane, i.e., the steady state of a resting nerve fibre
