The 4 major types of inhibition are  Competitive Inhibition, Non-competitive Reversible Inhibition,  Non-competitive Irreversible Inhibition, and  Uncompetitive Inhibition.

Types of inhibition modes:

1. Competitive Inhibition: Competing inhibitors are substances that resemble an enzyme's natural substrate so closely that they vie for the active site. In order to stop additional reactions, the inhibitor binds to the active site and stays there.

The inhibitor and substrate fight for the enzyme's active site because the enzyme may react with the inhibitor and release the products as it normally would with its substrate

2. Non-competitive Inhibition:

  • Reversible: There is no competition in this instance because the inhibitor and substrate are not related. The substrate and the inhibitor may mix at various places of the complexes of the enzymes [E-I], [E-S], and [E-I-S].

And in the Michaelis equation, this kind of inhibition lowers V max but has no impact on Km.The rate at which the enzyme is fully saturated is given by V = V max [S] / Km + [S] (V max).

(Km): The substrate is the Michaelis constant, at which the reaction rate is halved, or at V maximum.

  • Irreversible: These kinds of inhibitors impact the chemical alteration of an amino acid residue in the enzyme that plays a function in catalysis when they join with the enzyme nearby or at the active site.

       Additionally, this kind of inhibition lowers Vmax but has no impact on Km.

3. Uncompetitive Inhibition: is the last type, where the inhibitor attaches to the [E-S] complex to create [E-S-I] even if it has no affinity for the enzyme.

However, this kind of inhibition lowers both Vmax and Km.
