Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Glycoprotein
Concept:

Conjugated molecules are complex structures formed by the covalent bonding of two entirely different classes of biological macromolecules.

Solution:

  • A Glycoprotein is formed when short chains of carbohydrates (glyco-) are covalently bonded to a polypeptide backbone (protein).


  • Because it merges two distinct fundamental macromolecule groups into one functional unit (often used for cell surface recognition), it is officially classified as a conjugated molecule.


Why other options are incorrect:

  • Protein, Lipid, Vitamins: These are all simple, single-class molecules. They are not conjugated to a secondary, distinct chemical group.

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.
