A) \[{{K}^{+}}\] inward, \[N{{a}^{+}}\] outward
B) \[{{K}^{+}}\] inward only
C) \[N{{a}^{+}}\] inward only
D) \[{{K}^{+}}\] outward, \[N{{a}^{+}}\] inward
Correct Answer: A
Solution :
The cell membrane of the body have powerful \[N{{a}^{+}}-{{K}^{+}}\] pump that continually pumps sodium ions to the outside of the cell and potassium ions to the inside. In sodium potassium pump \[N{{a}^{+}}-{{K}^{+}}\] dependent ATP ase enzyme helps in translocation of three \[N{{a}^{+}}\] ions out of the cell for every two \[{{K}^{+}}\]ions pumped into the cell. ATP powers the changes in conformation by phosphorylating the transport protein.You need to login to perform this action.
