Due to the action of $Na^+/K^+$-ATPase pump.

Vedclass · Answer

(B) The intracellular concentration of $K^+$ is maintained higher than the extracellular concentration primarily through the action of the $Na^+/K^+$-ATPase pump.This pump actively transports $3$ $Na^+$ ions out of the cell for every $2$ $K^+$ ions it brings into the cell,utilizing energy from $ATP$ hydrolysis.Because more positive charges $(Na^+)$ are pumped out than are brought in $(K^+)$,the interior of the cell becomes negatively charged relative to the exterior.This electrochemical gradient,combined with the continuous activity of the pump,ensures that $K^+$ ions accumulate inside the cell at higher concentrations than in the extracellular fluid.

How is it that the intracellular levels of $K^+$ are higher than extracellular levels in animal cells?
