Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Glucose and fructose
Concept:

Hydrolysis of a disaccharide yields its exact original building blocks.

Solution:

  • Sucrose (common cane sugar / table sugar) is formed in plants by linking α-glucose and β-fructose.


  • When the enzyme sucrase catalyzes the hydrolysis of sucrose, it splits the α-1,2-glycosidic bond, releasing exactly one molecule of Glucose and one molecule of Fructose into the bloodstream.


Why other options are incorrect:

  • Glucose + Galactose: This is the hydrolysis product of Lactose, not Sucrose.


  • Lactose: Is a disaccharide itself; it is never produced by breaking down another disaccharide.

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.
