Question

The movement of molecules across a cell membrane using a membrane transport protein and cellular ATP energy, generally moving the molecules from a region of low to high concentration, is called

Answer 1

Active transport: moving against a gradient

To move substances against a concentration or electrochemical gradient, a cell must use energy. ... Primary active transport directly uses a source of chemical energy (e.g., ATP) to move molecules across a membrane against their gradient.
