Enzyme Catalysis Lab Questions Before answering these questions, make sure that you have graphed your results on the provided graph paper. (See step 9 of Procedure D) In addition, please calculate the class averages for amount of hydrogen peroxide used for each time period (10,30, 60, 120, 180 seconds) and graph this as a separate line on your graph. 1. Using the class average data, calculate the initial rate of reaction (0-10s). rate = amount of H2O2 consumed divided by time. Then calculate the rate of reaction for 10-30s, 30- 60s, 60-120s, and 120-180s. What happens to the reaction rate as time passes? Offer an explanation for this. 2. In part D, what was the function of each of the following: catalase, hydrogen peroxide, sulfuric acid, potassium permanganate? 3. Why was it important to establish a baseline in Part B?

Unformatted text preview: 4. What function do enzymes serve in living organisms? 5. Since enzymes function better under different conditions, where in the human body would you expect to find enzymes that work well in a low pH environment? 6. Within our bodies, would you expect the catalase that our body produces to function better in the summer or winter? Explain. 7. There is an enzyme called amylase that helps us digest starches. This enzyme’s optimal temperature is between 35-40 degrees Celcius. Predict what would happen to the rate of amylase activity at 20 degrees Celcius. 8. Do enzyme catalyzed reactions continue indefinitely? Why or why not? 9. There are many enzymes classified as proteases. What is a protease? What would happen if you added a protease to the catalase prior to conducting part D?...
