The structures scattered throughout the cell and controlling the release of energy from food to form ATP are mitochondria.

Here's why:

* Mitochondria are the powerhouses of the cell. They are responsible for cellular respiration, the process that breaks down glucose (from food) and converts its chemical energy into ATP, the primary energy currency of cells.

* They are scattered throughout the cytoplasm. This ensures that all parts of the cell have access to the energy produced.

* They have their own DNA and ribosomes, indicating their evolutionary origin from ancient bacteria that were engulfed by eukaryotic cells.
