      • remaining amino acids fed into cellular respiration
        • within mitochondria of liver cells
          • results in production of ATP and heat energy
    • detoxification
      • liver cells removing poison
        • e.g alcohol
        • breaks down into harmless chemicals
      • if paracetamol is overused
        • = liver failure
