Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Secondary lysosomes
Concept: Lysosomes undergo structural and functional changes once they begin actively digesting material.

Solution: When a newly formed (primary) lysosome fuses with a food vacuole or an autophagosome, it becomes an active digestive compartment known as a secondary lysosome.

Distractor Autopsy: Phagocytosis is the process of eating, not the organelle. Primary lysosomes are inactive (pre-fusion). Peroxisomes belong to a completely different class of microbodies.

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.
