Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Faster in aerobic respiration
Concept:

Cellular respiration is responsible for the production of ATP, but the efficiency and overall rate of productive yield depend heavily on the presence of oxygen.

Solution:

  • Aerobic respiration fully oxidizes a glucose molecule, generating 36 to 38 ATP per molecule.
  • Anaerobic respiration only yields 2 ATP per molecule.
  • Because aerobic respiration rapidly generates such a massive, sustained yield of ATP through the electron transport chain, its overall functional "production of energy" is considered significantly higher and effectively faster at meeting large metabolic demands.


Why other options are incorrect:

  • While anaerobic glycolysis can rapidly produce ATP in short bursts (like in sprinting muscles), it cannot sustain high-volume energy production, leading to rapid energy depletion compared to aerobic pathways.

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.
