Vedclass · Answer

(C) Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration (against the concentration gradient). This process requires metabolic energy,which is provided by $ATP$ (Adenosine Triphosphate). The energy is typically utilized by membrane-bound carrier proteins or $ATPase$ enzymes to pump solutes across the membrane.
