1) The activation energy is the energy required to get the reaction to the transition state. The transition state is the point during the reaction, the top of the graph, when the bonds are the most unstable and are very stressed. At this point, it is very easy for the reaction to occur because of the strain. The free energy change is what this diagram is graphing and it is measured by the amount of energy in a given system that can be either gained or lost. In this Exergonic reaction, energy is released more so than it is created and therefore the free energy graph goes down because the energy is leaving the system. 2) Enzymes are globular proteins that bind substrates and stress particular bonds in order to lower the activation energy of reactions and make these more likely. Because of this, enzymes make reactions much more efficient and time-consuming. Furthermore, since enzymes always retain their original shape after the reaction has taken place, they can continually be reused. The exergonic yield powers an enderognic one in enzymes so they are to some extent self-sufficient. 3) The Induced Fit model, as apposed to the ‘lock and key’ model, holds the theory that
