Answer

The mechanisms of enzyme catalysis begins when a substrate binds with an enzyme on its active site. The binding energy is used to decrease the contribution of the activation entropy by transferring the translational and rotational entropy of the reagent. Enzyme mechanisms also include providing an alternative reaction path in order to utilize energy more efficiently and dissolving ionic groups for both reacting and catalyzing materials.
