Enzymes and Catalysis. Enzymes are proteins that reduce the energy required to achieve the transition state (Figure 2). Enzymes reduce the activation energy through a process called catalysis. A biochemical reaction when an enzyme is present is called a catalyzed reaction. Catalysis can happen in different ways. Enzymes can use the transfer of protons or electrons to the reactants to modify the state of the reactants.
