Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Toxic effect of alcohol metabolism
Concept: Peroxisomal enzyme activity in cellular detoxification.

Solution: Catalase breaks down toxic hydrogen peroxide (\(H_2O_2\)) generated during oxidative reactions (including organic metabolite breakdown) into harmless water and oxygen, protecting the cell from oxidative damage.

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.
