10.2: The Equations of Enzyme Kinetics. In biological systems, enzymes act as catalysts and play a critical role in accelerating reactions many times faster than the reaction would normally proceed. Enzymes are high-molecular weight proteins that act on a substrate, or reactant molecule, to form one or more products.Michaelis-Menten kinetics: It describes the rate of an enzyme reaction by relating reaction rate to substrate concentration. V = Vmax [s]/KM + [s] Determination of KM and Vmax values required algebraic manipulation of the basic Michaelis-Menten equation. The value for Vmax forms a horizontal asymptote on the graph.The Michaelis-Menten equation is the most widely known model in enzyme kinetics: Where v0 is the initial reaction rate, [S] is the substrate concentration, Km is the Michaelis constant, and Vmax is the maximum reaction rate. The Michaelis constant describes the kinetics of substrate/enzyme binding. However, its precise meaning depends on what ...Investigate Alcohol Flush Malady by study Alcohol Dehydrogenase kinetics.
