1. Which of the following statements about the active site of an enzyme is correct?

The active site of an enzyme binds the substrate of the reaction it catalyses less tightly than it does the transition state intermediate.

The active site of an enzyme binds the substrate of the reaction it catalyses more tightly than it does the transition state intermediate.

Which of the following statements about the nature of enzyme catalysis is correct?

An enzyme can change the equilibrium position of the reaction it catalyses by lowering the energy of activation of that reaction.

D. An enzyme cannot change the equilibrium position of the reaction it catalyses but it lowers the energy of activation of that reaction.

Which of the following statements about Michaelis-Menten kinetics is correct?

Km, the Michaelis constant, is a measure of the affinity the enzyme has for its substrate.

Km, the Michaelis constant, is defined as the concentration of substrate required for the reaction to reach maximum velocity.

Which of the following statements about the competitive inhibition of an enzyme-catalyzed reaction is correct?

The Vmax for a reaction remains unchanged in the presence of a competitive inhibitor.

A competitive inhibitor and substrate can bind simultaneously to the enzyme

Which of the following statements about the mechanism of allosteric control of enzyme activity is correct?

Allosteric enzymes show greater sensitivity to changes in substrate concentration compared to classical type enzymes with hyperbolic kinetics.

Allosteric enzymes show reduced sensitivity to changes in substrate concentration compared to classical type enzymes with hyperbolic kinetics.

Which of the following statements about the nature of enzyme catalysis is correct?

The rate of formation of the transition state intermediate determines the overall free energy change of the reaction.

The rate of formation of the transition state intermediate determines the overall reaction rate.

Which of the following statements about Michaelis-Menten kinetics are correct?

A high Michaelis constant (Km) indicates a high affinity of an enzyme for its substrate

A low Michaelis constant (Km) indicates a high affinity of an enzyme for its substrate.

Free energy of activation

Energy difference between that of the reactant and transition state a high energy intermediate that occurs during the formation of product

Energy difference between that of the reactant and transition state a low energy intermediate that occurs during the formation of product
