C
pH of enzyme
D
Nature of enzyme

Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Nature of enzyme
Concept: High-energy radiation disrupts protein folding and tertiary stability.

Solution: Ionizing radiation disrupts internal hydrogen and disulfide bonds maintaining the tertiary structure of enzymes. This irreversibly denatures the protein, fundamentally altering the nature of the enzyme and permanently halting catalysis.

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.
