Mitochondria.
Pyruvate disintegrates into carbon dioxide and water in the mitochondria. This pyruvate conversion can be classified into three separate constituents of carbon dioxide along with water and energy which occurs within the mitochondria cristae. Inside the cristae, the cytochromes of the mitochondrion are the sites for this particular conversion. This is the reason why mitochondria is also referred to as a powerhouse of cells.
