Answer:
The answer is Mitochondria.
Step-by-step explanation:
Mitochondria are cytoplasmic organelles of eukaryotic cells, formed by a double menbrana, responsible for supplying most of the energy necessary for cellular activity, through the consumption of oxygen, and the production of carbon dioxide and water as products of the cellular respiration. Mitochondria act as power plants of the cell and synthesize ATP at the expense of metabolic fuels.
