  • Enzymes
    • Shape of an enzyme is vital for it's function.
      • High temperatures change the shape.
    • Different enzymes work best at different pH values.
      • The stomach produced hydrchloric acid.
        • Enzymes in the stomach work best in these acidic conditions.
    • Amylase enzyme
      • Produced in ...
        • Salivary glands
        • Panceas
        • Small intestine
      • Catalyses the breakdown of starch into sugars in the mouth and small intestine.
    • Protease enzyme
      • Produced by...
        • Stomach
        • Pancreas
        • Small intestine
      • Catalyse the breakdown of proteins into amino acids in the stomach and small intestine.
    • Lipase enzymes
      • Produced by the...
        • Pancreas
        • Small intestine
      • Catalyse the breakdown of lipids in fatty acids, glycerol in the small intestine.
    • Biological catalysts
      • Speed up chemical reactions
        • Not used up in the process.
    • Made up of amino acids
      • Joined together in long chains which are folded to produce a unique 3D structure
    • The part  of the enzyme to which the reactant binds in the active site
  • Bile
    • Produced in the liver
    • Stored in the glass bladder
      • Then released into small intestine
    • Neutralises acid in the stomach.
      • Provides alkaline conditions in which enzymes in the small intestine work best
