Light vs dark reactions
WebApr 6, 2024 · In the following phase of photosynthesis, the dark reactions, ATP and NADPH, are used to produce glucose from Carbon dioxide. The light reaction uses water, light (brought in from outside the cell), NADP+, phosphorus, and ADP (all created by the Calvin cycle) to produce ATP (both used in the Calvin cycle), and oxygen (a waste product). WebApr 9, 2024 · The nighttime reactions of photosynthesis are propelled by the energy provided by ATP (made during the light reactions). The phrase "dark reactions" does not imply that the reactions take place at night or that darkness is required. It means that the reactions can continue regardless of how much light is present.
