Potassium inside the cell and sodium out of the cell
<u>Explanation</u>:
The presence of the pump can be seen in plasma membrane of the animal cell. Which can be followed by the ATP, this pump pushes sodium and potassium in completely opposite direction that can be said as against the concentration gradient. In one cycle of this pump, two potassium are ingested inside the cell and three sodium are taken out from the cell. Due to more number of negatively charged proteins inside the cell, potassium ion contains more positive charge so pushed inside the cell. The potassium is pumped through the channels.
