Concept:The effect of competitive inhibitors relies purely on a statistical game of chance regarding which molecule collides with the active site first.
Solution:- A competitive reversible inhibitor weakly binds to the active site without permanently damaging it.
- Because it is a numbers game, if you drastically increase the concentration of the true substrate, the substrate molecules vastly outnumber the inhibitors.
- The sheer probability of a true substrate colliding with the active site becomes so high that the effect of the inhibitor is completely neutralized.
- (Note: The provided options historically list "Reversible inhibitor" as the correct choice for this competitive mechanism).
Why other options are incorrect:Any irreversible inhibitor (competitive or non-competitive) forms permanent covalent bonds that destroy the enzyme; adding more substrate cannot save a destroyed active site.
Quality & Fidelity Assurance:
Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
