BRAINCAKEActive Transport
Active Transport is the movement of molecules or ions into or out of a cell from a region of lower concentration to a region of higher concentration using ATP and carrier proteins.
Active transport differs from passive transport because it uses metabolic energy in the form of ATP and uses carrier proteins to selectively move ions and molecules against their concentration gradient.
