- - - - enzyme denatures - active site changes shape
        
        rate of reaction lowers
        
        fewer enzymes not denatured
        
        fewer enzyme- substrate complexes form
        
        Substrate cannot fit
    - - Lower Ek in substrate & enzyme
        
        Moving slower with less energy
        
        fewer successful collisions
        
        fewer enzyme-substrate complexes form
  - - - Enzyme denatures
        
        Substrate cannot fit
        
        Rate of reaction lowers
        
        Fewer enzymes not denatured
        
        Fewer enzyme-substrate complexes form
- - - - 3) Heat to correct temp in a water bath
        
        4) Combine the solutions and stir, immediately starting a stop watch and leave in the water bath
        
        At 30s intervals add a
        drop of solution to a well
        and continue until the iodine no longer turns blue-black
        
        this means the reaction has completed and starch is no longer present
        
        Repeat for different pH values of buffer solution
