The activity of the Hill reaction was also estimated after plant return to the …
WebMay 2, 2024 · The Hill Reaction depends on electrons released during the light-dependent stage of photosynthesis being picked up by the blue electron acceptor DCPIP. The reaction can only occur if the thylakoid membranes are illuminated as the light-dependent stage stops in the dark. DCPIP is blue when oxidised (at pH 7.0) and colourless when reduced, …
