Gerhart 10/29/2010 Unit 2 (Energetics) review questions Catalysts 1a. This value, together with the concentrations of the A and B dictate the rate of the forward reaction (choose one from a, b, c, d, or e above). What is the name for this value? 1b. This value is unaffected by heat or the presence of a catalyst (choose one from a, b, c, d, or e above). What is its name? 1c. At equilibrium this value dictates the value of the ratio ([A] x [B]) / ([C] x [D]) (choose one from a, b, c, d, or e above) 1d. This value is reduced by a catalyst but not by heat. (choose one from a, b, c, d, or e above) What is its name? 2. Explain the lock and key model of enzyme function, including the role played by the active site of the enzyme. 3. Draw an energy profile (like that shown in the figure for question 1) for an endergonic reaction. Alter the profile to show the affect of an enzyme. Label energy of activation, transition state, products, reactants, and Δ G. 4. What about proteins makes them suited for so many roles in a cell? 5. Some soluble proteins found in the cytoplasm contain a high number of hydrophobic amino acids. How would you predict that these proteins would fold (tertiary structure) and why? Metabolism Basics (Redox, ATP, NAD) 1. When a chemistry book presents electron shells, it generally emphasizes that shells represent distinct energy levels. Electron shells are also said to represent distance from the positive charges in the nucleus. Are these two viewpoints contradictory? Why or why not?
