Summary Introduction

To explain:

The net direction of ${\text{K}}^{\text{+}}$ movement in response to a decrease in $\text{pH}$.

Concept introduction:

The sodium-potassium channels are present in the membrane of cells which lead to the exchange of ions from the intracellular side to the extracellular side of the membrane and from the extracellular side to intracellular side of the membrane. It utilizes the energy of $\text{ATP}$ which opens the voltage-gated channels in the membrane.
