The type of transport that uses proteins to move large or charged molecules **AGAINST the concentration gradient** is called **Active transport**.

Active transport requires energy, typically in the form of ATP, to push molecules from an area of lower concentration to an area of higher concentration, which is contrary to the natural flow of molecules due to diffusion.
