The graph below shows energy profiles of the catalyzed and uncatalyzed conversions of reactants "A+B" to products "C+D". Use the graph below to answer the following "Part 1" questions about enzymes. A + B a. b. c. d. e. C + D Free Energy Progress of the Reaction a) Is converting "A+B" to "C+D" endergonic or exergonic? How do you know? (1) b) Which lowercase letter on the graph represents the ?G for the reaction? How do you know? (1) c) Which lowercase letter on the graph represents the activation energy of the uncatalyzed reaction? How do you know? (1) d) Could the addition of an enzyme to an endergonic reaction transform that endergonic reaction into an exergonic reaction? Explain why or why not. (2)

Activation Energy and Catalysis The graph shows three reaction pathways for the same biological reaction. One reaction pathway shows an uncatalyzed reaction, while two reaction pathways show catalyzed reactions, one catalyzed by enzyme X and one catalyzed by enzyme Y. For this particular biological reaction, enzyme X is a better catalyst than enzyme Y. Which statements apply to each reaction? Reactants Products Reaction pathway Drag each item to the appropriate bin: Catalyzed by enzyme X Fastest reaction Highest activation energy Catalyzed by enzyme Y Lowest activation energy Uncatalyzed reaction Slowest reaction Reaction A Reaction B Reaction C

The progress of a reaction from reactants to products is shown in the following diagram: Curve A Curve B Energy, kJ Progress of reaction (a) Which curve (A or B) represents the catalyzed reaction? (b) How many elementary steps are in the catalyzed reaction? (c) How many elementary steps are in the uncatalyzed reaction? (d) What is the activation energy Ea of the uncatalyzed reaction? (to the nearest kJ) (e) What is the activation energy of the catalyzed reaction? (to the nearest kJ) (f) What is Δ H for the reaction? (to the nearest kJ) (g) What is the activation energy of the reverse uncatalyzed reaction? (to the nearest kJ)

Draw a diagram of enzyme function with and without enzymes for the reaction: A + B -> transition state -> C + D + energy On the diagram, show: 1. Show the free energy of the reactants using horizontal lines. 2. Show the energy of activation (EA) both with and without an enzyme. Use letters A and B. Are the values the same? 3. Indicate the change in free energy (ΔG) of the reaction. Use letter C. Is it exergonic or endergonic?
