Answer:
d. neither the light reactions nor the Calvin cycle
Explanation:
Calvin cycle is the name given to a set of chemical reactions that occur in the chloroplast stroma. The chemical reactions that make up the Calvin cycle occur in the carbon fixation step, one of the photosynthesis phases. In this cycle, CO2 is reduced to glyceraldehyde 3-phosphate and ribulose 1.5 bisphosphate, CO2-acceptor, is regenerated.
Photosynthesis is initiated by light reactions, which use light energy to store and transport energy-supplying molecules such as ATP and NADPH.
Neither the Calvin Cycle nor light reactions requires glucose, these processes are initiated by other molecules and are intended to provide products for photosynthesis to occur.
