Question

In this type of inhibition, the inhibitor can bind to the enzyme regardless of whether the substrate has already bound to the enzyme or not. b) noncompetitive c) uncompetitive d) All of the above a) competitive e) None of the above

Answer 1

The correct option is : b) noncompetitive

Step-by-step 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.
