The correct option is C Allosteric inhibition
The correct option is option (C):
Explanation of the correct option:
- Allosteric inhibition is a type of inhibitory mechanism in which allosteric inhibitor binds with a special site in enzymes called allosteric site.
- By the attachment of allosteric inhibitors, enzymes change the shape and structure of the active site.
- This prevents the attachment of substrate with enzyme and thereby inhibits the action of enzyme.
Explanation of the incorrect option:
Option (A):
Reverse inhibition is a type of inhibition in which enzyme can regain their catalytic power after the inhibition mechanism.
Option (B):
Competitive inhibition is a type of inhibition in which the inhibitor competes with the substrate to attach to the active site of enzyme.
Option (D):
Non-competitive inhibition is that inhibition mechanism in which the inhibitor inhibits the enzyme activity without blocking the formation of the enzyme-substrate complex.
Final answer: Change of active site, which prevents the binding of substrate to an enzyme and stops the reaction is called Allosteric inhibition.
