- Inhibition of an enzyme is to inhibit the catalytic activity of the enzyme. - Because, by blocking or inhibiting an enzyme's activity can kill a pathogen or correct a metabolic imbalance. Example : Inhibition of HIV protease.

When a enzyme is inhibited (many proteins are enzymes), it just means that the enzyme will be reduced in its ability to catalyze a reaction. There are a few types of Inhibition like Competitive Inhibition, Noncompetitive Inhibition, and Irreversible Inhibition.

Ki = [I]/alpha - 1

competitive

There are two main types of feedback inhibition: competitive inhibition, where an inhibitor competes with the substrate for the active site of an enzyme; and non-competitive inhibition, where an inhibitor binds to a site on the enzyme other than the active site, altering the enzyme's shape and reducing its activity.
