In biology, is the movement of molecules or ions across a cell membrane from a region of lower concentration to a region of higher concentration . Because this movement goes against the concentration gradient , it requires the use of cellular energy, typically in the form of Adenosine Triphosphate (ATP) . How Active Transport Works In biology, is the movement of molecules or
