68 Richard Daley College Biology Lab Manual Mader Me Laboratory Review 5 1. What symbol represents the change that occurs in a chemical reaction? 2. Are the substrates in an enzymatic reaction reactants or products? 3. What is the name of the location on an enzyme where its substrate or substrates bind? 4. What cellular organelle contains catalase and is present in all plant and animal organs? 5. What did measuring the bubble column heights in all the experimental procedures indicate? What purpose did the tube containing water and hydrogen peroxide serve in the catalase activity experimental procedure? 6. 7. What word describes the loss of an earyme's original shape and ability of its active site to function? 8. What happens to enzyme activity if the temperature increases slightly? 9. What did the negative control tube lack when the effect of enzyme concentration was studied? 10. If cells produce more catalase, will there be more or less water and oxygen produced from the breakdown of hydrogen peroxide by catalase? 11. What word describes the pH at which the speed of a reaction involving an enzyme occurs best? 12. What does a shift in pH (too high or too low) do to an enzyme that will influence its activity? 13. In the Experimental Procedure on the effect of pH on enzyme activity, which tube contained water with an acidic pH? 14. Since enzymes are specific for certain substrates and often have similar nams, what is the name of the enzyme used in tube 3 of the catalase activity experiment that facilitates the breakdown of sucrose? Thought Questions 15. People with Crohn's disease may develop lactose intolerance caused by damage to their small intestine. These people may take a commercial product called Lactaid to prevent digestive upset when consuming dairy products. What is in Lactaid that helps these people avoid those symptoms? Explain how this relates to what you learned about the specificity of enzymes for substrates in this lab 16. High-grade fevers (in humans, 103°F or higher) are of concern, and medical care should be obtained. Explain why, based on your understanding of enzyme function.
