Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Collagen
Concept:

Macromolecules are composed of specific fundamental monomers. Proteins are polymers of amino acids.

Solution:

  • Collagen is the most abundant structural protein in the mammalian body, found extensively in connective tissues.


  • Because it is a protein, it is synthesized exclusively from amino acid monomers linked by peptide bonds.


Why other options are incorrect:

  • Cellulose & Sucrose: These are carbohydrates, composed entirely of monosaccharide sugars (glucose/fructose).


  • Ascorbic acid: Also known as Vitamin C, it is a small, water-soluble organic compound (a sugar acid), not a protein.

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.
