mitochondrion is the correct answer.

Explanation:

The organelle in eukaryotic cells that converts the energy stored in food in the chemical bonds of carbohydrate, fat, and protein into a form usable by the cell for all its functions and activities is a: mitochondrion.Mitochondria is the powerhouse of the cell and it is located in the cytoplasm. Mitochondria is responsible for the generation of adenosine triphosphate inside the cell and ATP produced is utilized by the cell to carry out different functions.Mitochondria function is to carry out cellular respiration it acts as a digestive system that carries in the nutrients and breaks down and generates energy-rich molecules for cells.
