Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Cinchona ledgeriana
Concept:

Industrial production of secondary metabolites in plant cell bioreactors.

Solution:

The antimalarial alkaloid compound quinine is produced at industrial scales using cell suspension cultures of Cinchona ledgeriana.

Why other options are incorrect:

  • Digitalis lanata: Cultured for the commercial production of cardiac glycosides like digoxin and digitoxin.


  • Nicotiana tabacum: Model plant system used for studying nicotine biosynthesis and transgenic transformation.


  • Glycine max: Soybean species used in agricultural biotechnology for seed storage protein and oil production.

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.
