Graph 2
Insert the graph of Activity 2 data.
2. Interpret the graph for Activity 2. Is there an optimum temperature for
catalase that makes it the most productive in terms of reaction rate? At what
temperature does the rate decrease? Explain why.
Graph 3
Insert the graph of Activity 3 data.
3. Interpret the graph for Activity 3. Is there an optimum pH for catalase that
makes it the most productive in terms of reaction rate? At what pH’s does the
rate decrease? Explain why.
