The catalytic efficiency of many enzymes depends on pH. Chymotrypsinshows a maximum value of kcat/KM at pH 8. Detailed analysis shows thatkcat increases rapidly between pH 6 and 7 and remains constant at higherpH. KM also increases rapidly between pH 8 and 10. Suggest explanationsfor these observations.

Polymerization Kinetics

Polymerization is a chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that diverge in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes. Polymerization is generally classified into step-growth and chain polymerization. Polymers are categorized into linear polymer and cross-linked polymers that are produced either by condensation or additional polymerization.
