WebThe Hill Reaction depends on electrons released during the light-dependent stage of photosynthesis being picked up by the blue electron acceptor DCPIP. The light-dependent … WebThe Hill reaction involves isolating chloroplasts from living cells and suspending them in a coloured electron acceptor. In this case, the electron acceptor is the blue dye DCPIP. The dye is blue when oxidised and colourless when reduced, so it is possible to monitor the loss of blue colour as an indication that DCPIP has accepted electrons.
