Against concentration gradient and requires $ATP$

Vedclass · Answer

(A) Active transport is a biological process where molecules or ions are moved across a cell membrane from a region of lower concentration to a region of higher concentration.This movement occurs against the concentration gradient.Because this process goes against the natural flow of diffusion,it requires the expenditure of metabolic energy in the form of $ATP$ (Adenosine Triphosphate).Therefore,active transport is characterized by movement against the concentration gradient and the requirement of $ATP$.
