1. The graph given shows the concentration of product formed (umol/L) vs. time (sec) in an enzyme-catalyzed reaction. (a) (1 point) What is the reaction rate between 0 and 10 seconds? Product concentrationum 10 20 40 50 60 30 Times (b) (1 point) How does the reaction rate change over time? Give explanation for your answer in the context of chemical kinetics. 2. (1 point) Based on the structure of MPG (shown in the background section), would MPG more likely be, a competitive or noncompetitive inhibitor for beta-galactosidase? Explain why. 3. (1 point) Lactose hydrolysis can be catalyzed not only by lactase but also by a chemical catalyst such as HCI. Which of the graphs below would correspond to each case? Explain your answer. 4.0 100 3.0 Rxn rate 20 Rxn rate M 1.0 30 Temperature Temperature 1.
