Peroxisomes hold on to enzymes that require oxygen (oxidative enzymes). Lysosomes have enzymes that work in oxygen-poor areas and lower pH. Peroxisomes absorb nutrients that the cell has acquired. They are very well known for digesting fatty acids. They also play a part in the way organisms digest alcohol (ethanol). Because they do that job, you would expect liver cells to have more peroxisomes than most other cells in a human body. They also play a role in cholesterol synthesis and the digestion of amino acids. Creating Hydrogen Peroxide Peroxisomes work in a very specific way. Their enzymes attack complex molecules and break them down into smaller molecules.
The diplomonads also lack peroxisomes and lysosomes. Lysosomes are membrane-enclosed sacs that hold digestive enzymes used in the digestion of macromolecules such as fats, polysaccharides and proteins. The lack of these enzymes might cause an indirect effect on the production of cellular components.The lack of peroxisomes might have a similar impact.iplomonads found in fish (SEM).
