Multiple Choice

Figure 6.2 Rate of an enzyme-catalyzed reaction as a function of varying reactant concentration, with the concentration of enzyme held constant.
-In Figure 6.2, why does the reaction rate plateau at higher reactant concentrations?

• A) Feedback inhibition by product occurs at high reactant concentrations.
• B) Most enzyme molecules are occupied by substrate at high reactant concentrations.
• C) The reaction nears equilibrium at high reactant concentrations.
• D) The activation energy for the reaction increases with reactant concentration.
• E) The rate of the reverse reaction increases with reactant concentration.
