There are 3 types of inhibition
1. Competitive inhibition
2. Non competitive inhibition
3. End product inhibition
1. Competitive inhibition
competitive inhibition are some what similar to the specific substrate of the enzyme and they can fit into the active site of enzyme.
competition occurs between the specific substrate molecule and inhibitor molecule to occupy active sites.
2. Non competitive inhibition
Non competitive inhibitors do not combine with the active site of the enzyme instead they fit into ALLOSTERIC SITE. Therefore substrate unable to combine with enzyme . As the enzyme substrate formation is affected reaction rate decreases . This inhibition cam be reversible or irreversible.
3. End product inhibition
When the end product of a series of reaction causes and inhibition over one or more enzyme of the path. It referred as end product inhibition.
