Answer:
D. Photosynthesis uses carbon dioxide while cellular produces carbon dioxide
The reactions of the Calvin cycle add carbon from carbon dioxide in the atmosphere to a five-carbon molecule known as RuBP. These reactions use chemical energy that were produced in the light reactions, from NADPH and ATP. The final product of the Calvin cycle is glucose.
The balanced equation would be
3H2 + N2 ———> 2NH3
