|Factors That Affect the Activity of Enzymes|
|A student conducted an experiment to measure the reaction rate of the enzyme catalase on a solution of hydrogen peroxide. In this reaction, the enzyme facilitates the breakdown of hydrogen peroxide into water and oxygen. The reaction is illustrated by the following chemical equation:
The release of oxygen causes a change in pressure which can be measured by a CBL apparatus. Data from this reaction are shown in the table below.

- Use the data provided to construct a line graph of this reaction. Be sure to include all of the elements specified on the "Scoring Criteria for Graphs" sheet.
- Next, select one of the following variables and describe how it would affect the rate of the reaction.
- The temperature drops
- The pH drops
- The substrate concentration increases
- Finally, draw a dashed line on the graph to illustrate the change that would occur.
