Dark Reactions

Dark Reaction

The dark reaction, or light-independent, known as the Calvin Cycle, is the second stage of photosynthesis, where plants use chemical energy to produce glucose. While this reaction does not use light directly, it depends on the energy-carrying molecules (ATP and NADPH) produced duri...

The energy carriers ATP and NADPH generated from light reactions initiate the second stage of photosynthesis, called the Calvin cycle. It was named after the scientist Melvin Calvin, who discovered it.

Because these reactions are light-independent, they're called dark reactions.

This cycle generates glucose and other carbohydrates, w...
