Chlorophyll and other pigments absorb light energy, which is converted into chemical energy:
Correct answer: B. ATP and NADPH
- A. NADH and NADPH
- B. ATP and NADPH
- C. ATP and NADH
- D. FADH and NADPH
Explanation
During the light-dependent reactions of photosynthesis, chlorophyll and other pigments absorb light energy, which is then converted into chemical energy stored in the form of ATP and NADPH. ATP acts as the energy currency, driving various cellular processes, while NADPH provides the reducing power needed for the synthesis of glucose in the Calvin cycle. Other options are incorrect because they include NADH and FADH, which are not involved in photosynthesis but rather in cellular respiration.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
