Answer:

the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy

Explanation:

In cellular biology, active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient. Active transport requires cellular energy to achieve this movement.
