Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Formation of energy rich carbohydrates
Concept:

The light-independent phase (Calvin cycle) uses the assimilatory power generated by the light reactions to fix carbon.

Solution:

  • In this phase, \( CO_2 \) is incorporated into organic molecules.
  • ATP and NADPH are consumed to reduce this carbon, leading to the formation of energy-rich carbohydrates (such as G3P).


Why other options are incorrect:

  • Hydrolysis of water, ATP generation, and production of reducing molecules (NADPH) strictly occur during the light-dependent reactions.

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.
