Michaelis–menten kinetic equations

WebbThe kinetic equations that describe trans-cleavage are known as the Michaelis-Menten system and are detailed in the Supplementary Information (S1). Under both the reactant stationary assumption[23] and the quasi-steady state assumption,[2] the reaction velocity is governed by the Michaelis-Menten equation: = 㑅 0㑆= 00㑆= 𝑘 WebbThe kinetic equations serve as a bridge between the microscopic domain and the behavior of macroscopic irreversible processes through the description of hydrodynamics in terms of intermolecular collisions. ... In the case if the dependence of the rate of a reaction step in a species X m has an upper limit, we use Michaelis-Menten kinetics.
