Which one of the following is true regarding our coverage of enzyme kinetics? Increasing the concentration of an enzyme is not expected to affect the Km of the enzyme. One strategy for increasing Vo if the enzyme is not already saturated is to reduce enzyme concentration. For a favorable reaction, the G value of a transition state has a value that is lower than the G value of the reactant but higher than the G value of the product. An enzyme that is a high-Km mutant has a slower turnover rate than the wild-type enzyme. Enzymes that obey Michaelis-Menten kinetics have approximately zero-order kinetics when [S] is 10% of Km or lower.

384 Enzyme Reactions and Kinetics Q6.3: What kinetic parameter reveals the most information about how well an enzyme works? Describe this kinetic parameter in terms of the turnover number and the Michaelis constant and provide an explanation for why triosephosphate isomerase is considered to be ~16,000 better than pepsin when this kinetic parameter is used to compare these two enzymes.
When an enzyme is added to a solution (1.0 mL) containing its substrate at a concentration of 100 times the Km, it catalyzes the conversion of 75 mol of the substrate into the product in 3.0 min in the 1.0 mL solution. The concentration of enzyme in the solution is 0.20 M. What is the enzyme's turnover number (kcat)? Note that the unit of kcat is min-1.
1) Discuss the transition state(s) in reaction coordinate diagram in the context of ΔG. 2) If an enzyme deceases the activation energy, ΔG‡, by the quantity X, we learned that the forward rate constant is increased by multiplication with the factor eX/RT. Why does this simple fact demonstrate that small changes in activation energy give big changes in catalyzed rates? 7)Two people study the same enzyme. They get different Vmax in each experiment, but the same kcat. Why?
