Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Electron transport chain
Concept: The folded inner membrane of the mitochondria maximizes surface area for ATP production.

Solution: The cristae (infoldings of the inner mitochondrial membrane) are studded with the protein complexes that make up the Electron transport chain (ETC) and ATP synthase. This is where oxidative phosphorylation occurs.

Distractor Autopsy: Glycolysis occurs in the cytoplasm. The Calvin cycle and photophosphorylation occur in the chloroplast.

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.
