Lab

The hypothesis is rejected because the reaction occurred slower then the control's reaction did. The reaction decreased. Not only that but the reaction did not last as long as the control's. At five minutes the reaction had stopped all together which might have been because there was no more substrate. It might have also been because of the high temperature the hydrogen peroxide was placed in, which is where the yeast was also held. Since the temperature was at 65 degrees Celsius, that might have been too high for the protein causing it to become denatured. Once denatured it loses its shape. No more substrate the reaction cannot continue. Connecting this lab to the real world, enzymes are found in many parts of the human body from the mouth, used to breakdown food this called saliva. To the stomach as well to the digestive system. These enzymes work best at certain temperatures, which is evident in the lab conducted. The body regulates the temperature which ensures that the enzymes work at their best and are not denatured.
