Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Mesosome
Concept: Without internal organelles, prokaryotes utilize inward folds of their plasma membrane to increase functional surface area.

Solution: Mesosomes are internal pouch-like invaginations of the bacterial plasma membrane. They hold respiratory enzymes and act as attachment points for the circular DNA, aiding in DNA replication and septation during binary fission.

Distractor Autopsy: Lysosomes and Golgi bodies are eukaryotic. Phragmoplasts are involved in eukaryotic plant cell wall formation.

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.
