• A) increasing the temperature has activated an inhibitor.
• B) the saturation rate was not determined at the optimal temperature.
• C) the increased temperature has removed a prosthetic group,thus activating the enzyme.
• D) the reaction is regulated by feedback inhibition.
• E) the subunits of the enzyme have denatured.
