    • The model than an enzyme acts upon is called its substrate
    • Enzyme reactions can be summarised by the equation: substrate+enzyme ---> products
    • enzyme molecules are folded into a special shape
    • Letter: A
    • Letter: C
    • Letter: D
    • Letter: A
    • Compared to the start of the reaction, the enzyme molecule at the end is exactly the same
    • the part of the enzyme molecule where the substrate fits in is called the active site
    • this picture of how enzymes work is sometimes called the enzyme substrate complex
    • for it's function, the shape of an enzyme molecule is essential
    • if an enzyme molecule is heated too much, it denatures-its shape is changed or destroyed
    • How enzymes behave at different temperatures is best summarised by: different enzymes work best at different temperatures
    • if an enzyme molecule is heated too high a temperature, it permanently stops working
    • how an enzyme behaves at different level of acidity is best summarised by: each enzyme has a PH that it catalyses fastest
