Question
Hydrogen peroxide (H2O2) is a toxic chemical (waste product) that is produced when our bodies break down amino acids and complete other important metabolic reactions. Catalase is an enzyme found in our livers that is responsible for the decomposition (break down) of hydrogen peroxide into the harmless compounds of water and oxygen. Due to the enzyme's action, the cells in our bodies are able to rid themselves of the harmful H2O2 waste product. Without the catalase enzyme, many of our cells would be damaged by the increased amount of H2O2. When the enzyme is working, oxygen gas bubbles will be released. The chemical reaction that occurs is the following: catalase 2H2O2 → 2H,O + O2 Students in biology class performed an experiment to test the activity of catalase at different pH levels. The diagram below represents the students’ results.

3. Based on the diagrams, which statement best supports the students' observations? A Exposing catalase to extremely high pH yields high enzyme activity. B Exposing catalase to extremely low pH yields no enzyme activity. OExposing catalase to neutral pH yields no enzyme activity. D Exposing catalase to a pH below 2 or above 10 yields maximum enzyme activity.

Expert Solution
Step 1

pH is a very important criteria for determining the activity of an enzyme because an enzyme only worke at its optimal pH range. Altering this pH range to extreme values may  denature the enzyme by disrupting various ionic  interactions which are required for proper enzyme substrate binding.
