After the NADPH molecules are formed, they bring pairs of the the molecules into the next part of photosynthesis. ... During this reaction, both the ATP and NADPH transform the carbon dioxide into carbohydrates. The carbon dioxide molecules come from the atmosphere and then enter the Calvin cycle
During the photosynthesis light dependent reactions make ADP and NADPH. They are used in the light independent cycle as energy used to carry on the reactions that break down the three carbon molecules. Twelve three-carbon molecules are formed from every six carbon dioxide molecule.
The key factor in determining the habitable zone of a planet is looking for a Earth-like planet that is able to have water on it's surface, and make sure that it can still give or support life.
