Potassium movement into cells always requires energy expenditure.

Question

Quizplus · Accepted Answer

Potassium movement into cells requires active transport, which involves the expenditure of energy (usually in the form of ATP). This is necessary because the concentration of potassium ions is typically higher inside cells than outside, so they must be actively transported against the concentration gradient. Without energy expenditure, potassium would simply diffuse out of cells and into the extracellular fluid, leading to disturbances in cell function and potential damage.
