The diagram shows the transport of ions across the cell surface membrane. Inside the cell there is a low concentration of sodium ions $\left( {N{a^ + }} \right)$ and a high concentration of potassium ions $\left( {{K^ + }} \right)$.
Outside the cell there is a low concentration of ${K^ + }$ and a high concentration of $N{a^ + }$.
The carrier molecule is a pump which exchanges $N{a^ + }$ for ${K^ + }$.
Which ionic movements are represented by the arrows?
A
2 )
B
3 )
C
4 )
D
