Which one of the following statements is incorrect ?
The competitive inhibitor does not affect the rate of breakdown of the enzyme-substrate complex.
The presence of the competitive inhibitor decreases the Km of the enzyme for the substrate.
A competitive inhibitor reacts reversibly with the enzyme to form an enzyme-inhibitor complex.
In competitive inhibition, the inhibitor molecule is not chemically changed by the enzyme.
As we discussed in
Competitive Inhibitor -
When the chemical inhibitor closely resembles the substrate in its molemolec structure and inhibits the activity of enzyme is konwn as Competitive Inhibitor.
-
Competetive inhibitor mimics substrate and decreases the Km of the enzyme for the substrate.
Option 1)
The competitive inhibitor does not affect the rate of breakdown of the enzyme-substrate complex.
Incorrect option
Option 2)
The presence of the competitive inhibitor decreases the Km of the enzyme for the substrate.
Correct option
Option 3)
A competitive inhibitor reacts reversibly with the enzyme to form an enzyme-inhibitor complex.
Incorrect option
Option 4)
In competitive inhibition, the inhibitor molecule is not chemically changed by the enzyme.
Incorrect option
