The organelle that uses energy from food to make high-energy compounds is the mitochondrion.

Here's why:

* Mitochondria are the powerhouses of the cell. They are responsible for cellular respiration, the process that breaks down glucose (sugar) in the presence of oxygen to produce ATP (adenosine triphosphate).

* ATP is the primary energy currency of cells. It's used to power many cellular processes, such as muscle contraction, protein synthesis, and active transport.
