Unlike primary active transport, secondary active transport does not require an ATP molecule to function.

Explanation:

Active transport is the movement of molecules across a cell membrane from a region of their lower concentration to a region of their higher concentration—in the direction against some gradient or other obstructing factor.

In some cases it is possible to couple the transport of two different molecules across a membrane so that the energetic effects cancel one another out. In this case the ultimate source of energy is the force causing the initial concentration gradient.
