Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Murein
Concept: Different domains of life utilize distinct biochemical polymers for their cell walls.

Solution: The bacterial cell wall is primarily composed of peptidoglycan, also known as murein. It consists of sugars cross-linked by short peptides.

Distractor Autopsy:
  • Cellulose: Found in plant and algal cell walls.
  • Chitin: Found in fungal cell walls and arthropod exoskeletons.

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.
