CBH 15 and 16 peroxisomes and mitochondria

• Characteristics of peroxisomes

  Spherical and limited by one membranepresent in every cell type except in Erythrocytes, abundant in liver and kidneydiameter: 0.3-1.5 micrometerdo not contain DNA

  
• Enzymatic content in peroxisomes

  Oxidases, that catalyse oxidation reactionscatalase degrades hydrogen peroxide, which is damaging to the cell
• Functions of peroxisomes

  Beta-oxidation of fatty acids (complement mitochondria)synthesis of some lipids( bile acids and cholesterol)detoxification of potentially harmful molecules, particularly in kidney and liver
• formation of peroxisomes

  
• Location of mitochondria

  Basal infolding in distal convoluted tubule(in the kidney)in skeletal muscle, there are many mitochondria near the contractile apparatusin sperm, it is found around the flagellum
• Structure of mitochondria
