Question

Does photosynthesis use ATP?

Answer 1

Photosynthesis uses ATP.

1. Light-dependent reactions use light energy to produce two molecules needed for the next step of photosynthesis: $\mathrm{ATP}$ an energy storage molecule, and$\mathrm{NADPH}$, a reduced electron carrier.
2. $\mathrm{ATP}$ is used in the biosynthesis step or carbon fixation during photosynthesis.
3. The Calvin cycle uses $18\mathrm{ATP}$s molecules to produce one glucose molecule.

Final Answer: Photosynthesis uses ATP.
