    • Describe how enzymes catalyze biochemical reactions.

    This plot shows that a catalyst decreases the activation energy for a reaction but does not change the Gibbs free energy.

    In this diagram, a substrate binds the active site of an enzyme and, in the process, both the shape of the enzyme and the shape of the substrate change. The substrate is converted to products that then leave the enzymes active site.
