Mitochondria are main sites of aerobic respiration. They are miniature biomolecular factories where food stuffs or respiratory substrates are completely oxidised to carbon dioxide and water. The energy liberated in the process is stored in the form of ATP.
Because of formation of ATP mitochondria are called <em>power</em><em> </em><em>hou</em><em>se</em><em> </em><em>of</em><em> </em><em>th</em><em>e</em><em> </em><em>cell</em>.
