Original Khojo Papers practice question — not from a past board paper.
Answer
The light reaction occurs in the grana of the chloroplast, needs light, splits water and produces oxygen, ATP and NADPH. The dark reaction occurs in the stroma, does not itself need light, and uses the ATP and NADPH to reduce carbon dioxide to carbohydrate.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The dark reaction cannot go on indefinitely in the dark, because it depends on the products of the light reaction.
