Competitive inhibitor resembles closely with the substrate and competes for the active binding site of the enzyme.
The presence of competitive inhibitor decreases the affinity of the substrate to binding site of the enzyme which results in increase of Michaelis-Menten constant (km).
Competitive inhibitor resembles closely with the substrate and competes for the active binding site of the enzyme.

Explanation:
Presence of Competitive Inhibitor and Km:
- The statement that the presence of the competitive inhibitor decreases the Km of the enzyme for the substrate is incorrect.
- Competitive inhibitors do not affect the Km of the enzyme for the substrate. Instead, they compete with the substrate for binding to the active site of the enzyme.
Competitive Inhibitor Interaction:
- A competitive inhibitor reacts reversibly with the enzyme to form an enzyme-inhibitor complex.
- This complex formation prevents the substrate from binding to the enzyme's active site, reducing the enzyme's ability to catalyze the reaction.
Chemical Change in Competitive Inhibition:
- In competitive inhibition, the inhibitor molecule is not chemically changed by the enzyme.
- The inhibitor simply competes with the substrate for binding to the enzyme's active site, without undergoing any chemical modification itself.
Effect on Rate of Enzyme-Substrate Complex Breakdown:
- The competitive inhibitor does not affect the rate of breakdown of the enzyme-substrate complex.
- Instead, it primarily affects the formation of the enzyme-substrate complex by competing with the substrate for binding to the enzyme.
Therefore, the correct statement among the options provided is that the presence of the competitive inhibitor does not decrease the Km of the enzyme for the substrate.
