For Many Enzymes, the Rate of Product Formation Increases as the Concentration

question 47

Multiple Choice

For many enzymes, the rate of product formation increases as the concentration of the substrate increases. Eventually the rate of the reaction reaches a maximum at which further increases in the concentration of the substrate have no effect. Why?

• A)At high concentrations of substrate, all of the enzyme molecules are bound to substrate molecules.
• B)At high concentrations of substrate, the activation energy of the reaction increases.
• C)At high concentrations of substrate, the activation energy of the reaction decreases.
• D)The enzyme is no longer specific for the substrate.
• E)At high concentrations of substrate, the reaction is endergonic.
