WebbLa cinetica di Michaelis-Menten descrive l'andamento della velocità di una reazione catalizzata da enzimi, al variare della concentrazione del substrato e dell'enzima. Questo modello, valido per enzimi non allosterici, fu proposto da Leonor Michaelis e Maud Menten nel 1913. [1] WebbThree assumptions are implicit in Michaelis-Menten kinetics: the steady-state approximation, the free ligand approximation and the rapid equilibrium approximation. (The Briggs-Haldane approach frees us from the last of these three.) Now consider the second assumption in the list: the free ligand approximation.
