Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: 0
Concept:

Glycolysis is divided into an energy-investment (preparatory) phase and an energy-payoff phase.

Solution:

  • During the preparatory phase, the cell must spend energy to phosphorylate the glucose molecule, consuming 2 ATP.
  • Because ATP is consumed and not generated during this phase, the number of ATP formed is exactly 0.


Why other options are incorrect:

  • 4 ATP are formed later in the payoff phase.
  • 2 ATP represents the amount consumed, not formed.

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.
