Active transport is the movement of molecules across a cell membrane across a concentration gradient from a region of lower concentration to a region of higher concentration. To achieve this movement, active transport necessitates the use of cellular energy. The technique of transporting molecules across a cellular membrane using cellular energy is known as active transport. Active transport transports molecules from a lower concentration to a higher concentration, whereas passive transport can only move molecules from a higher concentration to a lower concentration. ive transport necessitates the use of cellular energy to accomplish this movement. A protein pump uses energy in the form of ATP to move molecules from a lowconcentration location to a high- concentration location during active transport
