Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Sucrose
Concept:

Understanding the natural biological sources of common commercial sugars.

Solution:

  • Sugarcane is specifically cultivated globally to extract the common dietary sugar stored heavily in its stalks.


  • This specific transport and storage sugar manufactured by the plant is the disaccharide Sucrose (a 1:1 dimer of glucose and fructose).


  • (Table sugar is almost 100% pure crystallized sucrose extracted from sugarcane or sugar beets).


Why other options are incorrect:

  • While Glucose and Fructose are the fundamental building blocks within the plant, they are immediately bonded together and stored massively in the stalk as the larger Sucrose molecule.

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.
