✅ Correct Answer:
C) They generate ATP and NADPH

Rationale:

The light-dependent reactions:

Occur in the thylakoid membranes of chloroplasts

Convert light energy → chemical energy (ATP/NADPH)

Involve:

Photosystems II and I
Electron transport chain
ATP synthase (photophosphorylation)

Produce oxygen as a byproduct (from water photolysis)

Key Products:

ATP (energy currency)
NADPH (reducing power)
Both are used in the Calvin cycle

Why the other choices are incorrect:

❌ A) Occur in stroma - Incorrect. The stroma hosts the Calvin cycle, while light reactions occur in thylakoids.

❌ B) Produce glucose - Incorrect. Glucose synthesis occurs in the Calvin cycle using ATP/NADPH.

❌ D) Fix CO₂ - Incorrect. CO₂ fixation is catalyzed by RuBisCO in the Calvin cycle.

36:T4da,

✅ Correct Answer:
C) To synthesize glucose from carbon dioxide

Rationale:

The Calvin cycle (light-independent reactions) performs carbon fixation by:

Incorporating CO₂ into organic molecules (via RuBisCO)

Using ATP and NADPH from light reactions

Producing glyceraldehyde-3-phosphate (G3P) - the precursor for glucose

Key Features:

Occurs in the stroma of chloroplasts
Consists of 3 phases:
- Carbon fixation
- Reduction

Why the other choices are incorrect:

❌ A) Produce oxygen - Incorrect. O₂ is released during water photolysis in photosystem II.

❌ B) Convert light energy - Incorrect. Light → chemical energy conversion occurs in thylakoid membranes.

❌ D) Split water - Incorrect. Water splitting is part of the light-dependent reactions.
