What does NADPH2 provide during photosynthesis?
Correct answer: A. Energized electrons
- A. Energized electrons
- B. Uncharged electrons
- C. Energy
- D. All of these
Explanation
NADPH, produced during the light-dependent reactions of photosynthesis, provides high-energy electrons and hydrogen ions to the Calvin cycle. These electrons are crucial for the reduction of carbon compounds, leading to the synthesis of glucose. Options B and C are incorrect because the Calvin cycle requires specifically energized electrons, not uncharged ones or standalone energy. Option D is incorrect as NADPH does not provide all of these; it specifically provides energized electrons.
