Question

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.

Answer 1

Answer:

B

Explination:

After determining the optimum pH, they could vary the temperature of the environment to see if catalase is temperature specific. Proteins can be denatured through exposure to heat, changes in pH, or chemicals. Students could vary the temperature of the liver, even boil it, to see if enzyme action continued.

Answer 2

B) After determining the optimum pH, they could vary the temperature of the environment to see if catalase is temperature specific

Enzymes are proteins which catalyze reactions by acting on substrates in order to speed up reactions-  like the breakdown of large polysaccharides by amylase. Here, the enzyme catalase facilitates the breakdown of hydrogen peroxide into oxygen and hydrogen. Catalase specificity is affected by pH, temperature and the presence of inhibitors.

In temperatures beyond its optimal range, catalase may undergo changes to its physical structure called denaturation; when denatured, enzymes lose their ability to bind specifically to their substrate -i.e. substrate binding specificity is lost.  H2O2 would no longer be able to bind to the active site, and thus would not be broken down.
