Question: what is dpip in photosynthesis?
Answer: In this experiment, a blue dye (2,6-dichlorophenol-indophenol, or DPIP) will be used to replace NADPH in the light reactions. When the dye is oxidized, it is blue. ... Since DPIP replaces NADPH in the light reactions, it will turn from blue to colorless when reduced during photosynthesis.
