This is a process by which cells move materials across their membranes against a concentration gradient, from an area of lower concentration to an area of higher concentration. This process requires energy, typically in form ATP (adenosine triphosphate).
congrats on reading the definition of Active Transport. now let's actually learn it.
ATP (Adenosine Triphosphate): This is often referred to as "molecular currency" for intracellular energy transfer; it transports chemical energy within cells for metabolism.
Endocytosis: A type of active transport where cells absorb material from outside by engulfing it with their cell membrane.
Exocytosis: Another type of active transport where cells expel waste materials or secretory products by vesicles fusing with plasma membrane and releasing their contents outside the cell.
