Correct answer is option 'A'. Can you explain this answer?
Verified Answer
The ultimate gain of light reaction is :-a)ATP & NADPH2b)NADPH2c)O...
The energy of light captured by pigment molecules called chlorophylls, in chloroplasts is used to generate high- energy electrons with great reducing potential. These electrons are used to produce NADPH2 as well as ATP in a series of reactions called the light reactions because they require light.

The Light Reaction of Photosynthesis
The light reaction is the first stage of photosynthesis, occurring in the thylakoid membranes of chloroplasts. Its primary function is to convert light energy into chemical energy.
Key Products of the Light Reaction
- ATP (Adenosine Triphosphate):
- Acts as an energy currency in the cell.
- Generated through photophosphorylation during the light-dependent reactions.
- NADPH2 (Nicotinamide Adenine Dinucleotide Phosphate):
- Serves as a reducing agent in the Calvin cycle.
- Produced by the reduction of NADP+ using electrons derived from water splitting.
- Oxygen (O2):
- Released as a byproduct during the photolysis of water.
- While essential for aerobic respiration, it is not the ultimate gain.
Overall Importance of ATP and NADPH2
- Both ATP and NADPH2 are crucial for the subsequent phase of photosynthesis, the Calvin cycle.
- They provide the necessary energy and reducing power for the synthesis of glucose from carbon dioxide.
Conclusion
Thus, the ultimate gain of the light reaction is both ATP and NADPH2, making option 'A' the correct answer. These products are indispensable for fueling the processes of life, particularly in photosynthetic organisms.
