Which of the following unexpected results could occur if you used the catalase before it had a chance to reach your experimental temperature:
a. in the experiment in which the enzyme was supposed to be boiled, you would get a higher bubble column than expected
b. in the experiment with cooled enzyme, you would get no enzyme activity
c. in the experiment with cooled enzyme, you would get higher bubble column than expected
d. in the experiment with over-heated enzyme, you would get no enzyme activity
