Question

What is the implication when we say that the enzyme is fully occupied by a substrate? How does adding more enzyme and substrate influence the rate of the chemical reaction?

Accepted Answer

Fully occupied substrate: All active sites of the enzyme are filled with reactant molecules

Adding More substrate: No change in the rate of the reaction

Adding More enzyme: Increases the rate of the reaction

Answer

Fully occupied substrate: Half of the active sites of the enzyme are filled with reactant molecules

Adding More substrate: Increases the rate of the reaction

Adding More enzyme: Decreases the rate of the reaction

Answer

Fully occupied substrate: All active sites of the enzyme are empty

Adding More substrate: No change in the rate of the reaction

Adding More enzyme: Increases the rate of the reaction

Answer

Fully occupied substrate: All active sites of the enzyme are filled with product molecules

Adding More Reactants: Decreases the rate of the reaction

Adding more enzyme: Increases the rate of the reaction
