Allosteric enzyme curve
WebEnzyme kinetics graph showing rate of reaction as a function of substrate concentration for normal enzyme, enzyme with a competitive inhibitor, and enzyme with a noncompetitive inhibitor. For the competitive inhibitor, Vmax is the same as for the normal enzyme, but … 1. Allosteric competitive: i: enzyme + inhibitor -/-> no reaction because … WebJun 10, 2024 · Allosteric enzymes often display sigmoidal plots of the reaction rate V0 versus substrate concentration [S], rather than the hyperbolic plots displayed by enzymes that do obey Michaelis-Menten kinetics. Allosteric enzymes often have multiple subunits each with an active site that binds and catalyses the reaction.

WebThis shifting of the equilibrium is responsible for the observed allosteric effects. The Monod–Wyman–Changeux model has been shown mathematically to explain the sigmoidal effects seen with allosteric enzymes. The shape of the curve will be based on the L and c values. As L increases (free T form more highly favored), the shape becomes more ... http://jiwaji.edu/pdf/ecourse/biotechnology/ALLOSTERIC%20ENZYMES.pdf
