From the graph, we can conclude that catalase has a low activity at low temperatures. Activity increases a little at 30°C and this process is the highest at 40°C, after this temperature, activity disminishes again.
Options:
A. This option is wrong because the number of bubbles at this temperatures is low, maybe the enzyme is already denatured.
B. This answer is wrong, at 30°C the enzyme shows a low activity.
C. This answer is correct because at this temperature the enzyme produces the higher amount of bubbles.
D. The activity of the enzyme at 0°C was not tested.
