Key Point #5 Enzymes have an optimum temperature and pH at which they work best
Key Point #6 Denaturation = proteins lose their tertiary structure and can no longer function properly –Temperature too hot –pH too acidic or basic –UV light –Anything that breaks chemical bonds
Key Point #7 Enzymes have names that end in “-ase” –Examples: Amylase Lactase – breaks down lactose Sucrase – breaks down sucrose Pectinase – breaks down pectin Helicase – breaks down helixes
