The organelle associated with the production of energy by aerobic respiration is the mitochondrion.

Here's why:

* Aerobic respiration requires oxygen to break down glucose and produce ATP, the cell's energy currency.

* Mitochondria are often called the "powerhouses" of the cell because they contain the enzymes and machinery necessary for the complex chemical reactions of aerobic respiration.
