Labster enzyme kinetics.

The Michaelis constant, K m, is a parameter in the Michaelis-Menten equation.K m is equal to the substrate concentration where the corresponding reaction rate is ½ • V max.An enzyme with a low K m, therefore, achieves its half-maximal velocity at a low substrate concentration, while an enzyme with a high K m needs high substrate concentrations to achieve this velocity.Chapter 12: Enzyme Kinetics.

Reversible inhibition results from a substance that binds to an enzyme and limits its capacity to catalyze reaction. The binding is non-covalent and reversible, and if inhibitor is removed, normal activity is restored.The concentration of inhibitor, like substrate, is typically much higher than enzyme concentration. Enzymes need to be regulated in the course of normal metabolism, i.e. an ...
