Experiment 2 Exercise 1A: Effect of substrate concentration on enzyme function

Review the Week 2 Experiment Introductions, our online lecture on Energetics and pp 80 - 82 in your book. For this exercise, we are going to look at the effect of substrate concentration on enzyme function, while holding enzyme concentration, pH and temperature constant. Open the following website to get started:

Glencoe- McGraw Hill. No date. Enzyme-controlled Reactions http://glencoe.mcgraw-hill.com/sites/dl/free/0078759864/383930/BL_11.html

Procedure

A. Click on the TV/VCR and listen to the short overview about enzyme action. Close the window when done.

B. Then click on the Information button and review the information there. Close the window when done.

C. In our first experiment, we will determine the effect of different amounts of substrate on enzyme function. First, we need to set up the experiment:

a. Click on the 0.5 g substrate weigh paper and drag it to Tube #1; note the color change. When our enzyme breaks down the substrate, the solution turns blue. The intensity of the color indicates the amount of product formed.

b. Now drag the 1.0 g substrate weigh paper to Tube #2 and continue as such with the rest of the substrate samples as indicated in the table below.

c. Click on the computer monitor to view your results and transcribe them to Table 1 below.

Table 1. Substrate amount and product formation results (1 pts).

D. Generate a scatter plot of Amount of Substrate vs Molecules of Product Formed and paste it here. Be sure you label your axes and include units. If you need help generating a graph, see the tutorials mentioned in the Week2 Experiment Introduction (3 pts).

Questions

1. In this Experiment, which variable is the dependent variable and which is the independent variable (2 pts)?

2. Describe the relationship between substrate concentration and enzyme function (as estimated by product formation) as evidenced by your graph above (1 pts).

3. What is the maximum rate of product formation and at what substrate level did this occur (1 pts)?

Experiment 2 Exercise 1b: Effect of pH on enzyme function

Be sure to review the Week 2 Experiment Introduction, our online lecture on Energetics and pp 80 - 82 in your book. For this experiment, we are going to look at the effect of pH on enzyme function, while holding enzyme concentration, substrate concentration and temperature constant. Go to:

Procedure

A. Click on Reset if necessary before beginning.

B. In our second experiment, we will determine the effect of pH on enzyme function. First, we need to set up the experiment:

a. First, you will need to adjust the pH in each test tube.

i. Use the up or down arrows beneath the test tubes.

ii. Set Tube #1 at pH 3 and Tube #2 to pH 5. Leave Tube #3 at pH 7. Set Tube #4 to pH 9 and Tube #5 to pH 11.

iii. Your test tube rack should now look like this:

C. Click on the paper containing 4.0 g of substrate and add it to each tube. Note that the amount of substrate is now a control variable and we add the same amount of substrate to each tube.

D. Click on the computer to view your results and transcribe your data to Table 2 below.

Table 2. pH and product formation amounts (1 pts).

E. Generate a scatter plot in of pH vs Molecules of Product Formed and paste it here. Be sure you label your axes and include units (3 pts).

Questions

1. In this Experiment, which variable is the dependent variable and which is the independent variable (1 pts)?

2. Describe the relationship shown in your graph between pH and enzyme activity. At what pH did you see optimum enzyme activity (2 pts)?

3. Explain your results based on what you have learned about enzymes this week and the factors that affect their function. Cite your source (1 pts).

Experiment 2 Exercise 2: Cellular Respiration and Photosynthesis

a. Hypothesis - Aquatic animals require the presence of plants to provide them with oxygen (via photosynthesis) needed for cellular respiration. <--READ first and then copy and paste it into the Hypothesis box in the Notebook.

The relationship mentioned in the hypothesis is illustrated in the diagram below:

In our experiment, we are using an aquatic environment, but the concepts are the same. The snails and Elodea will produce carbon dioxide via cellular respiration. The Elodea will use this carbon dioxide in photosynthesis to produce sugars. The oxygen required for cellular respiration will be generated by the Elodea via photosynthesis.

E. Leave the Notebook open and click on the tab next to Procedure (Step 1 of 7) to advance to Step 2.

F. Fill in the text boxes in the Lab Notebook by copying and pasting the information in italics below. You will need to use the slider on the right side of the Notebook to scroll down the page:

a. In my experiment, I will measure the level of CO2 by: bromothyol blue. Recall that in the presence of carbon dioxide, it will turn yellow.

b. In my experiment, my independent variable will be: The presence or absence of snails, the presence or absence of Elodea, and the use of light and dark.

c. The set-up condition for my control condition is: A test tube containing BTB.

d. I will use 8 test tubes.

e. Determine the set-up for each tube (Note the letters D and L refer to Dark and Light treatments):

Tube 1D: BTB only Tube 2D: BTB + 1 snail Tube 3D: BTB + 1 Elodea Tube 4D: BTB + 1 snail + 1 Elodea Tube 1L: BTB only Tube 2L: BTB + 1 snail Tube 3L: BTB + 1 Elodea Tube 4L: BTB + 1 snail + 1 Elodea

NOTE: Tubes 1-4D and 1-4L consist of the same treatments, except that one set will be placed in the dark (D) and the other in the light (L).

G. Close the Lab Notebook and click on the tab next to Procedure (Step 2 of 7) and advance to Step 3 and follow the lab set-up outlined above.

a. Distribute eight test tubes into the rack. Click on the box of test tubes and drag each one to the test tube rack.
