Certain environmental changes can denature proteins. denatured proteins lose their three dimensional structure and when the protein is an enzyme, they lose their ability to function. ph is just one factor that can change the effectiveness of an enzyme. what other factor might the students test regarding catalase specificity?

a) students could test various other enzymes to see if all enzymes were denatured in a basic environment (ph = 13).
b) after determining the optimum ph, they could vary the temperature of the environment to see if catalase is temperature specific.
c) after determining the optimum ph, the students could vary the amount of catalase used while keeping the amount of substrate constant.
d) students could test an assortment of food items besides liver, raw potato, apple, crackers, to see if catalase is consistently ph specific.
