Figure 2.18: The reaction represented by this graph involves the reactants glucose (C 6 H 12 O 6 )
and oxygen (O 2 ). The products of the reaction are carbon dioxide (CO 2 ) and water (H 2 O).
Energy is also released during the reaction. The enzyme speeds up the reaction by lowering
the activation energy needed for the reaction to start. Compare the activation energy with
and without the enzyme. ( 24 )
