Enzymes problems 1. Choose the best description of an enzyme: It allows a chemical reaction to proceed extremely fast. It increases the rate at which a chemical reaction approaches equilibrium relative to its uncatalyzed rate. It makes a reaction thermodynamically favorable. 2. What is the relationship between the rate of an enzyme-catalyzed reaction and the rate of the corresponding uncatalyzed reaction? Do enzymes enhance the rates of slow uncatalyzed reactions as much as they enhance the rates of fast uncatalyzed reactions? 3. Which type of enzyme (Table 11-2) catalyzes the following reactions? COO соо- NH NH3 (b) Coo CH3 CH3 (ToLIA 1 I ?) ootakr as the following reactions? (next naơe)
