Mitochondria produce energy through the process of cellular respiration. Respiration is another word for breathing. The mitochondria take food molecules in the form of carbohydrates and combine them with oxygen to produce the ATP. They use proteins called enzymes to produce the correct chemical reaction.
Mitochondria are known as the powerhouse of the cell because they contain enzymes that are needed for stepwise oxidation of food stuffs (carbohydrate, fats and lipids) present â¦ in the cells to CO2 and water. Oxidation of food releases energy which is used to form high energy ATP (adenosine triphosphate) molecules.he organelle that serves as the powerhouse of the cell is the  Mitochondria. Mitochondria are tiny organelles inside cells that  are involved in releasing energy from food, â¦ also known as cellular  respiration. Answered. In Genetics.
