Assertion (A): Competitive inhibitors bind to the active site of an enzyme, preventing substrate binding.
Reason (R): Competitive inhibition can be overcome by increasing the concentration of the substrate.
  • a)
    If both Assertion and Reason are true and Reason is the correct explanation of Assertion
  • b)
    If both Assertion and Reason are true but Reason is not the correct explanation of Assertion
  • c)
    If Assertion is true but Reason is false
  • d)
    If both Assertion and Reason are false
Correct answer is option 'A'. Can you explain this answer?

Assertion (A): Competitive inhibitors bind to the active site of an en...
- The Assertion is correct because competitive inhibitors indeed bind to the active site of an enzyme, which prevents the substrate from binding.
- The Reason is also correct as increasing the substrate concentration can outcompete the inhibitor for the active site, thereby restoring enzyme activity.
- Additionally, the Reason effectively explains the Assertion as it describes how competitive inhibition can be mitigated, confirming that both statements are true and that the Reason is the correct explanation for the Assertion.

Understanding Competitive Inhibition
Competitive inhibitors play a crucial role in enzyme activity and regulation. Let's break down the assertion and reason provided.
Assertion (A): Competitive inhibitors bind to the active site of an enzyme, preventing substrate binding.
- Competitive inhibitors are molecules that resemble the substrate and compete for binding at the enzyme's active site.
- When a competitive inhibitor occupies the active site, the actual substrate cannot bind, leading to decreased enzyme activity.
Reason (R): Competitive inhibition can be overcome by increasing the concentration of the substrate.
- Increasing substrate concentration effectively outcompetes the inhibitor for the active site.
- As the substrate concentration rises, more substrate molecules can bind to the enzyme, thereby restoring enzyme activity and overcoming the inhibition.
Conclusion: Why Option A is Correct
- Both the assertion and reason are true. Competitive inhibitors indeed bind to the active site, and their effects can be mitigated by increasing substrate concentration.
- The reason provided correctly explains the assertion, as the mechanism of competitive inhibition directly relates to the ability to overcome it by increasing substrate levels.
Summary
- Competitive inhibitors block substrate binding at the active site.
- Increased substrate concentration can alleviate the effects of competitive inhibition.
- Therefore, both assertion and reason are true, with the reason serving as the correct explanation for the assertion.
In conclusion, option 'A' is the correct choice as it reflects the relationship between competitive inhibition and substrate concentration effectively.
