The organelle that produces the energy required for active transport is the mitochondrion.

Here's why:

* Active transport moves molecules against their concentration gradient, which requires energy.

* Mitochondria are the powerhouses of the cell, responsible for producing ATP (adenosine triphosphate).

* ATP is the primary energy currency of cells, providing the energy for various cellular processes, including active transport.

So, the mitochondria generate the ATP that fuels the pumps and other mechanisms involved in active transport.
