A student did an experiment to test the activity of the enzyme sucrase in different conditions. He added the same amount of
sucrose, sucrase, and a buffer of pH 5.6 to two separate test tubes. He then incubated the first test tube at 35°C and the second
test tube at 100°C. The student's results indicated that only the first test tube showed enzyme activity. Which statement best
explains the student's results?
O A. A temperature of 100°C is not high enough to activate the sucrase enzyme.
OB.
A temperature of 100°C is high enough to denature the sucrase enzyme.
О с.
A pH of 5.6 is acidic enough to denature the sucrase enzyme.
O D. ApH of 5.6 is not acidic enough to activate the sucrase enzyme.
