PART 1: MEASUREMENT OF ENZYME ACTIVITY What color change happened when you mixed the first two tubes? Was the color change instantaneous or gradual? What did the blank tube for this experiment contain; what was missing, and why? When you mixed the enzyme and substrate tubes together the second time, did the absorbance continue to increase with time; or did it plateau? Explain why. Part 2: FACTORS THAT AFFECT ENZYME ACTIVITY Which factor will your group be investigating? Based on your understanding of enzyme activity, predict how this factor will influence the activity of the turnip peroxidase.

You have four tubes, each tube has the same amount of substrate, buffer, enzyme, and water to make the final volume in each reaction. You add enzymes and incubate each tube (1) for 5 seconds tube (2) 10 seconds tube (3) 20 seconds tube (4) for zero seconds. You add 25 uL iodine to each tube at the time indicated to stop the reaction and measure the absorbance. What is a hypothesis for this experiment? A. Enzyme produces more product if it has a longer reaction time B. The enzyme reaction is affected by different temperatures C. The amount of substrate affects the rate of the reaction D. None of these hypothesis

The rate of the enzyme-catalyzed reaction (measured as the amount of product produced during a given period of time) will be proportional to the intensity of color developed in each reaction mixture. Record your results by indicating the intensity of color in each tube after five minutes (0 indicates no change from original color; +, ++, and +++ indicate increasing intensities of color). Table 8A-4 Rate of Enzyme-catalyzed Reaction b. Do your observed results support the idea that an enzyme has a maximum velocity at which it would work? Explain.
