Proteosome vs Peroxisome
Proteosome is a proteasome (enzyme) that is used to degrade unneeded or damaged proteins. Occur in the cytoplasm and nucleoplasm - use ubiquitin.
Peroxisomes - (an organelle) - that uses molecular oxygen to oxidize organic molecules, enzymes to produce organic molecules, and enzymes to produce or degrade hydrogen peroxide. DO NOT have DNA, need to import all proteins. Neurons have NO peroxisomes. Major function is to rid the body of toxins, big in the liver.
