Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Condensation
Concept:

Building massive polymers from simple monomers requires a specific type of linking reaction.

Solution:

  • When plants convert excess glucose into massive starch (or cellulose) chains for storage, they must link thousands of monomers together.


  • They do this via Condensation reactions (specifically, dehydration synthesis).


  • In this process, an \(-OH\) is removed from one glucose, and an \(-H\) from another, forming a covalent glycosidic bond and expelling a molecule of water as a byproduct.


Why other options are incorrect:

  • Hydrolysis: The exact opposite; using water to break down the polymer.


  • Oxidation / Glycolysis: Metabolic pathways dedicated to tearing glucose apart to release energy, entirely opposite to synthesizing a storage polymer.

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.
