This act of lowering the activation energy needed for a reaction to occur allows them to be classified at catalysts. The enzyme itself, although, is a protein (Pfeiffer).3.13: Introduction to Enzyme Kinetics. Enzyme kinetics studies the rates of biochemical reactions. Scientists monitor the reaction rates for a particular enzymatic reaction at various substrate concentrations. Additional trials with inhibitors or other molecules that affect the reaction rate may also be performed.

Alcohol Dehydrogenase (ADH) is the enzyme that catalyzes the first step in the metabolism of alcohol in humans. ADH catalyzes the oxidation of a broad range of substrates containing hydroxyl groups, including ethanol. In the case of ethanol, the alcohol is converted into acetaldehyde, another toxic compound, which is then metabolized further.
