Enzyme kinetics

Common card · No. 437563

Enzyme kinetics is the scientific study of chemical reactions caused by enzyme catalysis, and a subfield of biochemistry. It is concerned with the reaction rate of chemical reactions, their effects, and the varying conditions that cause the reactions. Studying an enzyme's kinetics in this way can reveal the catalytic reaction mechanism of this enzyme, its role in metabolism, how its activity is controlled, and how a drug or a modifier (inhibitor or activator) might affect the rate. An enzyme, often written "E" in reactions, is a protein molecule that serves as a biological catalyst to facilitate and accelerate a chemical reaction in a cell or other biological environment. It does this through binding of one or more other molecules, its substrate (S), which the enzyme acts upon to form the desired product. The substrate binds to the active site of the enzyme to produce an enzyme-substrate complex (ES), and is transformed into an enzyme-product complex (EP) and from there to the product or...
