In the study of enzyme kinetics, the units Km and Vmax are measurements used to represent the rate of enzymatic reactions. Typically Vmax represents the maximum reaction rate achieved by the system, while Km is the substrate concentration at half the reaction rate of Vmax.Continue Reading
Enzyme kinetics is an essential part of biochemistry because enzymes are the protein catalysts that speed the rate of chemical reactions. The effect is achieved as the enzyme temporarily binds to the substrate and lowers the amount of activation energy required to convert the chemical.
Enzyme conversion rates are influenced by several other factors, including the concentration of substrate molecules, the presence of inhibitors and the temperature of the solution. The study of these rates is known as enzyme kinetics.
The system of measurement used is known as Michaelis-Menten kinetics, and it is named for the German biochemist Leonor Michaelis and the pioneering Canadian physician Maud Menten, who both made significant contributions to the study of enzyme kinetics and histochemistry.Learn more about Measurements
