WebPeroxisomes have a single membrane that surrounds the digestive enzymes and dangerous byproducts of their work (hydrogen peroxide). The protein enzymes are usually created by lysosomes floating in the cell. They then insert the proteins into the peroxisome bubble. Peroxisomes continue to grow until they split in two. WebLysosomes play the role of digestive component and organelle-recycling facility in animal cells. In addition, we consider them to be parts of the endomembrane system.
