Question:
Identify the correct statement with respect to enzyme competitive (X) and non-competitive (Y) inhibitors.
Identify the correct statement with respect to enzyme competitive (X) and non-competitive (Y) inhibitors.
Show Hint
Competitive inhibitors compete with the substrate for the active site, while non-competitive inhibitors bind to an allosteric site and change the enzyme's conformation.
Updated On: Mar 18, 2026
- Both X and Y bind to active site
- Both X and Y bind to allosteric site
- X binds to active site and Y binds to allosteric site
- X binds to allosteric site and Y binds to active site
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Competitive inhibitors (X) bind to the active site of the enzyme, competing with the substrate for binding. Non-competitive inhibitors (Y), however, bind to a site other than the active site, known as the allosteric site, and affect enzyme activity by altering its structure. Hence, the correct statement is that X binds to the active site and Y binds to the allosteric site.
