Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: 32
Concept: ATP accounting in cellular respiration.

Solution: Out of 36 net ATP generated per glucose molecule, 4 ATP are produced via substrate-level phosphorylation (2 in glycolysis, 2 in Krebs cycle). The remaining 32 ATP are derived via oxidative phosphorylation in the electron transport chain.

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.
