2. Average reaction rate data from the Energy and Enzymes lab
3. Graph and analyze this data

H.W. Study for tomorrow's CH.2 TEST AND put together your Ch. 2 Unit Packet (this includes the Ch. 2 Super Review)-  Click on the link to open and print or copy the table of contents.  Points will be deducted if this is missing.
AND Finish the Energy and Enzymes Lab:

–Pre lab questions

–Hypotheses

–Procedure pictures with the completed summary of test tube contents table.

–Completed data table

–Graph: 

Graph your data:  Create 1 graph for your data using graph paper.

Obtain the class averages for the rate of reaction for your period.  USING GRAPH PAPER, graph the class average reaction rate (change in temperature per second) data for Test Tubes #1-#6.  This should be a bar graph.  Graph the reaction rate as your y-axis and test tube contents as your x-axis.  When labeling your test tube contents on the x-axis be specific in what the contents were.  For ex. 5 mL H₂O₂,_, Raw Liver + 5 mL H₂O_2,etc… be specific! DO NOT just label the contents test tubes #1, #2…  Be sure to include a title, axis labels and a key (if necessary).  Identify the independent variables and the dependent variables.

–Analysis questions: 
Analysis: On your separate paper, under the data table, write the heading ANALYSIS.  Then answer the questions below in complete sentences.

1. Describe at least two things that you observed that would indicate a chemical reaction occurring.  Which liver sample had the most vigorous chemical reaction? Was this reaction endothermic or exothermic ; support this answer with data you gathered from the lab?

2. In your graph, you compared the reaction rate of hydrogen peroxide breakdown without an enzyme to the reaction rate of hydrogen peroxide breakdown in the presence of the enzyme catalase.  What conclusions can you draw from the graph of your data?  How do the rates of these two test tubes compare (see calculation in data table)?

3. In your graph, you used data from catalase at room temperature, in cold water, and catalase that had been cooked.   

                  a. Use the data from the lab to describe which temperature was the closest to catalase’s optimal reaction temperature.

                 b. Using vocabulary that you learned in class, describe what happened to the catalase in the cooked liver.  What effect did this have on the rate of the reaction in Test Tube #4?

                  c.  How did the cool temperature impact the rate of reaction for catalase?  Justify your answer using data from the lab and your knowledge of what happens to molecules as they cool down.

4. In your graph, you used data from catalase in water and catalase in vinegar.  How did vinegar affect the catalase?  Justify your answer using data from your lab/graph and your knowledge of pH and proteins from class.

5. In your graph, you used data from 5mL of hydrogen peroxide exposed to catalase as compared to 10mL of hydrogen peroxide exposed to catalase.  What did you change in this part of the lab?  What effect did this change have on the reaction rate?  Justify your answer using data from your lab/graph and information that you’ve learned in class.

6. Using page 52 in your book to help you, draw a series of pictures to show how catalase binds to hydrogen peroxide to create water and oxygen as products.  Label enzyme, catalase, active site, substrate, products, hydrogen peroxide, water, and oxygen in the illustration.  Make sure that the picture represents the catabolic reaction that occurred in this lab. 

7.  Draw another picture that shows catalase  at room temperature and another picture that shows catalase after exposure to high heat (aka boiling) or acidic pH.
