A researcher proposes a model of an enzyme-catalyzed reaction in which a reactant is converted to a product.
Enzyme catalysis is the increase in the rate of a process by a biological molecule, an "enzyme". Most enzymes are proteins, and most such processes are chemical reactions. Within the enzyme, generally catalysis occurs at a localized site, called the active site.
The model is based on the idea that the reactant passes through a transition state within the enzyme-substrate complex before the reactant is converted to the product.
