Active transport is the movement of molecules up their concentration gradient , using energy. The concentration of most molecules inside a cell is different than the concentration of molecules in the surrounding environment.
The transport proteins integrated into the cell membrane are often highly selective about the chemicals they allow to cross. Some of these proteins can move materials across the membrane only when assisted by the concentration gradient, a type of carrier-assisted transport known as facilitated diffusion.
