Detailed explanation-1: -“Active Transport is defined as a process that involves the movement of molecules from a region of lower concentration to a region of higher concentration against a gradient or an obstacle with the use of external energy.”
Detailed explanation-2: -Active transport is the movement of molecules across a cell membrane from a region of their lower concentration to a region of their higher concentration.
Detailed explanation-3: -Active transport is the movement of molecules across a cell membrane in the direction against their concentration gradient, i.e. moving from an area of lower concentration to an area of higher concentration.
Detailed explanation-4: -The only way that ions can move against their concentration gradient (from low to high) is through the use of cellular energy (ATP; active transport).
