The method of transport that moves substances in or out of cells requiring energy is known as active transport. Active transport mechanisms utilize energy, typically in the form of ATP (adenosine triphosphate), to move molecules against their concentration gradient. This means substances are moved from an area of lower concentration to an area of higher concentration, which is the opposite direction of passive transport processes such as diffusion or facilitated diffusion, where substances move along their concentration gradient without the use of energy. Examples of active transport include the sodium-potassium pump and proton pumps.
