Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Lysosomes
Concept: Genetic absence of specific degradative enzymes leads to lethal cellular hoarding.

Solution: Tay-Sachs is a fatal genetic disorder caused by the malfunction of lysosomes. Specifically, a mutation causes the absence of the lysosomal enzyme hexosaminidase A, leading to a toxic buildup of lipids in the neurons of the brain.

Distractor Autopsy: Glyoxysomes break down fatty acids in plant seeds. ER and Golgi are not the primary sites of terminal macromolecule degradation.

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.
