Vedclass · Answer

(A) 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 (against the concentration gradient).This process requires metabolic energy,typically in the form of $ATP$,to pump substances against their gradient.Passive transport,on the other hand,occurs along the concentration gradient and does not require energy expenditure.
