1 MCB 32 F09 Chapters 4 and 5, Energy Production and Metabolism Study Guide Chapter 4 Define : enzymes, coenzyme, reactants and products of a chemical reaction, ATPase, kinase, oxidation and reduction of NAD and FAD and their roles as electron carriers, effects of substrate concentration, temperature and pH on enzymatic reactions; effects of substrate vs reactant concentration on reversible reactions; “storage” of energy in ATP bonds 1. T-F? Enzymes are usually composed of carbohydrates. 2. T-F? Enzymes are produced on ribosomes. 3. Enzymes increase rates of reaction by a. Decreasing activation energy of the reaction b. Increasing the affinity of the substrates for the products c. Oxidizing the reactants 4. Rates of enzyme-catalyzed reactions are dependent on: a. substrate or reactant concentration b. temperature c. pH d. all of the above 5. T-F? ATP hydrolysis releases ADP, P i , energy and heat. 6. T-F? ATP synthesis consumes ADP, P i , energy and heat. 7. T-F? ATPase is an enzyme that can hydrolyze ATP. 8. T-F? Kinaes are enzymes that catalyze transfer of phosphate from ATP onto proteins. 9. T-F? Chemical reactants usually bind to enzymes at regions where the reactants are close together. 10. T-F? NAD and FAD can become oxidized by accepting electrons from hydrogen atoms removed from other molecules. 11.
