It also helps to produce adenosine triphosphate (ATP). Think of you when you lack oxygen in your body, you cannot perform its functions well, due to oxygen deficiency, the same happens with potassium and your plant, having a low potassium level causes its roots not to distribute its nutrients, it performs its photosynthesis and it does not even grow due to the little CO2 it receives.
