Light-independent reactions take place in plant chloroplasts. In this process sugars are made from carbon dioxide. The process, known as the Calvin cycle, uses products of the light-dependent reactions (ATP and NADPH) and various enzymes.
These reactions, known as the Calvin cycle, are called dark reactions because they do not use... The dark reactions of photosynthesis produce sugar phosphate molecules with three carbon atoms each. These reactions, known as the Calvin cycle, are called dark reactions because they do not use... The dark reactions of photosynthesis produce sugar phosphate molecules with three carbon atoms each. These reactions, known as the Calvin cycle, are called dark reactions because they do not use light energy directly, but they still depend on the energy captured from light and only occur during the day.
