Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Mitochondria
Concept: Aerobic respiration requires specialized compartments to maintain the proton gradients necessary for ATP synthesis.

Solution: The mitochondrion is the "powerhouse of the cell." It houses the Krebs cycle in its matrix and the Electron Transport Chain on its inner membrane, making it the absolute requirement for aerobic cellular respiration.

Distractor Autopsy: Plastids perform photosynthesis (in plants). The ER synthesizes lipids and proteins. The nucleus stores genetic material.

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.
