Lysosome vs Peroxisome

http://sln.fi.edu/qa97/biology/cells/cell7.html

"Peroxisomes contain oxidative enzymes. They are similar to lysosomes. Their enzymes have two functions; to convert fats to carbohydrates and to detoxify potentially harmful molecules which form in the cell.

Peroxisomes, in contrast to lysosomes, are produced only on the smooth ER system. They are found in the cytoplasm of many eukaryotic cells as well as prokaryotic cells, microorganisms, and plant cells.

The enzymes of peroxisomes remove hydrogen atoms from small molecules and joins them to oxygen creating hydrogen peroxide (toxic), which is later neutralised by a peroxisomal enzyme, catalase. In the liver this method is used to break down molecules of alcohol into substances that can be eliminated from the body. "
