Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Collagen
Concept:

Connective tissues rely heavily on extracellular fibrous proteins to resist mechanical stress.

Solution:

  • Collagen is the primary structural protein secreted into the extracellular space.


  • It forms an incredibly dense, tough fibrous network (matrix) that acts as the physical scaffolding for cartilage, tendons, ligaments, and the calcified structure of bone.


Why other options are incorrect:

  • Hemoglobin & Myoglobin: Globular proteins strictly dedicated to oxygen transport/storage.


  • Fibrinogen: A soluble plasma protein that converts to fibrin to facilitate blood clotting, not bone structure.

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.
