C) Active transport
D) Exocytosis
E) Diffusion

Active transport is the process used to move ions or molecules across a cell membrane against their concentration gradient, meaning from an area of lower concentration to an area of higher concentration. This process requires energy, typically in the form of ATP, because it is moving substances against the natural direction of diffusion. Sodium ions are commonly transported out of cells using active transport mechanisms, such as the sodium-potassium pump, to maintain essential cellular functions and the overall ionic balance within the body.
