Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Chloroplast
Concept: Autotrophs fix inorganic carbon into organic sugar using light energy.

Solution: In eukaryotic plants and algae, the chloroplast is the site of both the light-dependent reactions and the light-independent reactions (Calvin cycle). The Calvin cycle acts as the "factory" that utilizes ATP, NADPH, and $\text{CO}_2$ to synthesize sugars (G3P/glucose).

Distractor Autopsy: Mitochondria break down sugar. Amyloplasts store sugar as starch. Ribosomes make proteins.

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.
