WebFeb 4, 2024 · This stage is called the dark reactions because it does not require light energy, and it occurs in the absence of light. In the dark reactions, carbon dioxide is combined with a five-carbon sugar called ribulose bisphosphate (RuBP) to form a six-carbon intermediate. This intermediate is then reduced and split into two molecules of 3-carbon ... WebBoth reactions, the light-depended reaction and the Calvin's cycle OCCURS ONLY in the light (and out of color spectrum, mainly blue and red colors are used thus green reflected into your eye). 1. Light-depended reaction gives you the NADPH 2. You need NADPH in Calvin's cycle And you don't get the NADPH without light.
