Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Pyruvate
Concept:

Glycolysis is a universal pathway that is identical regardless of whether oxygen is present or absent.

Solution:

  • The pathway of glycolysis specifically ends with the formation of two molecules of Pyruvate (pyruvic acid).
  • What happens to the pyruvate afterward (e.g., turning into lactate or ethanol) is defined as the fermentation phase, which occurs after glycolysis.


Why other options are incorrect:

  • Ethanol and Lactate are end products of fermentation, not glycolysis itself.
  • Acetyl CoA is formed during the transition reaction in aerobic environments.

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.
