Part E : Lab Report

Directions : You will be directed to print your lab report, or share it electronically. This may be done as a group lab report.

A. Summary of Conclusions:

Use your data directly to explain what happened during your inquiry. Refer to specific data points. Describe any issues that occurred during your investigation. Use complete sentences and paragraph form.

SAMPLE DATA:

1. Trial 1: Just Enzyme , 10 min, 10% hydrogen peroxide, 25 mL of catalase.

Provide graph and data, describe results

2. Trial 2: just enzyme, what concentration ?

Provide Graph and data, describe results

NOTE : Provide the same info for any trials that you did.

3. Include your graphs and analysis of your graphs.

B. Questions :

1. What is the optimal pH for catalase? Does your data support this? Refer to your data, and explain your answer.

2. What is the optimal temperature for catalase action? Does your data support this? Refer to your data in your explanation.

3. At what temperature is catalase denatured? Give data points that support this. Explain what is happening to an enzyme like catalase when it is denatured?

4. What is the chemical reaction that catalse is catalyzing? ( Hydrogen peroxide was in your flask.)

5. How would the plot of the data appear if the experiment was performed without catalase?

6. Web Research : Where is catalase found in the human body?

7. Web Research : The rate of formation and release of product is called "Turn Over Number." For many enzymes the number is 1,000 molecules per second. What are the turn over numbers for these enzymes :

a. Carbonic anahydrase

b. Amalyase

c. DNA Polymerase

d. Catalase
