Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Lysosomes
Concept: Cellular digestion must be compartmentalized to protect the rest of the cell from damage.

Solution: Lysosomes fit this exact morphological and functional description. They are single-membrane bound vesicles (spherical sacs) packed with acidic hydrolytic enzymes capable of breaking down all biological polymers.

Distractor Autopsy: Golgi bodies are flattened stacks (cisternae). Mitochondria and chloroplasts are double-membrane structures.

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.
