Which of the following molecules are released after completion of light reaction and then utilized in the dark reaction of photosynthesis?
Correct answer: D. ATP and NADPH
- A. ATP and NADP+
- B. ADP and NADP+
- C. ADP and NADPM
- D. ATP and NADPH
Explanation
After the completion of light reactions in photosynthesis, the molecules released and utilized in the dark reactions are ATP and NADPH (Option D). These molecules provide the energy and reducing power required for the Calvin cycle, which is part of the dark reactions.

About Plant Nutrition and Transport
Plants require macronutrients and micronutrients for growth, and mineral deficiencies produce recognizable symptoms. Transport involves water and minerals through xylem by transpiration pull, cohesion and adhesion, while phloem translocates sugars from sources to sinks. Root pressure and transpiration are distinct mechanisms.
