WebMichaelis-Menten enzymes are different from allosteric enzymes (discussed in the main article on enzyme regulation). Allosteric enzymes typically have multiple active sites and … WebThe Michaelis constant (Km) is defined as the substrate concentration when the velocity of the reaction reaches one-half Vmax. In most cases, Km is a measure of the affinity of the enzyme for the substrates. The Michaelis-Menten equation can be used to generate a plot for any enzyme that Vmax and Km are defined. Both Vmax and Km are constants ...

WebMar 5, 2024 · The Michaelis-Menten equation is a mathematical model that is used to analyze simple kinetic data. The model has certain assumptions, and as long as these assumptions are correct, it will accurately model your experimental data. The derivation of the model will highlight these assumptions. WebKM (the Michaelis constant; sometimes represented as KS instead) is the substrate concentration at which the reaction velocity is 50% of the Vmax . [ S] is the concentration of the substrate S. WebWhen the value of the Michaelis constant is numerically equal to the substrate concentration the reaction rate is half of . Biochemical reactions involving a single substrate are often assumed to follow Michaelis–Menten kinetics, without regard to the model's underlying assumptions. Only a small proportion of enzyme-catalysed reactions have ... such as for example for instance
