So there are many different types of protein enzymes found inside the Paroxysome. And one of the major function, one of the major roles of the Paroxysome is to basically break down fatty acids into a type of energy source. So it basically creates ATP. So the mitochondria is not the only place in the animal cell where we create ATP. Paroxysomes can also create ATP by breaking down the fatty acids. Now, not only can we break down fatty acids inside Paroxysomes, we can also synthesize lipids, for example, cholesterol, inside our Paroxysomes.
