Vedclass · Answer

(B) Active transport is the movement of molecules or ions across a cell membrane from a region of lower concentration to a region of higher concentration,which is against the concentration gradient.Because this process moves substances against their concentration gradient,it is not a spontaneous process.Therefore,it requires the expenditure of metabolic energy,typically in the form of $ATP$ hydrolysis,to drive the transport proteins.As a result,active transport is sensitive to factors that affect cellular metabolism,such as temperature and metabolic inhibitors.
