Answer:
The correct option is : b) noncompetitive
Explanation:
There are three main types of inhibition:
1. Competitive: In this inhibition, the inhibitor molecule competes with the substrate to bind on the active site of the enzyme.
2. Uncompetitive: In this inhibition, the inhibitor molecule binds to the enzyme- substrate activated complex and thus, does not compete with the substrate to bind on the active site of the enzyme.
3. Non-competitive: In this inhibition, the inhibitor molecule can bind to both the enzyme molecule or to the enzyme-substrate activated complex.
Therefore, In non- competitive inhibition, the inhibitor molecule binds to the enzyme regardless of whether the substrate molecule is bound to the enzyme active site or not.
