Enzyme Amylase Protease Lipases Ra te OF enz ym e ac tivi ty Sites of production salivary glands pancreas small intestine stomach pancreas small intestine Pancreas small intestine LOCK and key model 1 The enzymes active site is a specific shape 2 the enzyme( the lock) will only catalyse a specific reaction because the substrate(the key) fits into it's active site 3 At The active site, enzymes can break molecules down into smaller or bind small molecules together to form larger ones 4 when the products have been released the enzymes active site can accept Another substrate molecule. Factors affecting enzymes: Enzymes Enzymes are large proteins that catalyse reactions. Enzymes are not changed in the reactions they catalyse. optimum temperature Temperature At lower temperature = Fewer successful collisions Enzymes+ substrates have less kinetic energy Digestive Enzymes = low activity = less substrate turned into product Attemp above optimum/more collisions Lipids → Fatty acids and glycerol Active site being deformed by higher temperature = number of successful collisions decreases (substrate + active site no longer complementary) All enzymes denatured = no activity Reaction catalysed starch →glucose Protein → amino acids Increasing temperature: More successful collisions Enzymes+ substrate have more kinetic energy = more substrate turned into product Enzyme Enzyme Enzyme Active Site substrate Inewrowy →>> substrate fits Into enzyme →>> Products realesed
