Which one of the following statements is incorrect?

1. A competitive inhibitor reacts reversibly with the enzyme to
form an enzyme inhibitor.
2. In competitive inhibition, the inhibitor molecule is not chemically
changed by the enzyme.
3. The competitive inhibitor does not affect the rate of breakdown
of the enzyme-substrate complex.
4. The presence of the competitive inhibitor decreases the km of
the enzyme for the substrate.

Hints

Select the option which is not correct with respect to enzyme action:
 

1. Substrate binds with the enzyme at its active site.
2. Addition of a lot of succinate does not reverse the inhibition of succinic dehydrogenase by malonate
3. A non-competitive inhibitor binds the enzyme at a site distinct from that which binds the substrate 
4. Malonate is a competitive inhibitor of succinic dehydrogenase
