Michaelis-menten curve
WebbThe Michaelis–Menten equation is mainly used to characterize the enzymatic rate at different substrate concentrations, but it is also widely applied to characterize the … The Hill coefficient is a measure of ultrasensitivity (i.e. how steep is the response curve). The Hill coefficient, or , may describe cooperativity (or possibly other biochemical properties, depending on the context in which the Hill–Langmuir equation is being used). When appropriate, the value of the Hill coefficient describes the cooperativity of ligand binding in the following way: • . Positively cooperative binding: Once one ligand molecule is bound to the enzyme, its affinity f…

In biochemistry, Michaelis–Menten kinetics is one of the best-known models of enzyme kinetics. It is named after German biochemist Leonor Michaelis and Canadian physician Maud Menten. The model takes the form of an equation describing the rate of enzymatic reactions, by relating reaction rate Visa mer In 1901, French physical chemist Victor Henri found that enzyme reactions were initiated by a bond (more generally, a binding interaction) between the enzyme and the substrate.
