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. WebReaction I is the classic Hill reaction. Operation of PS I in isolation can be achieved by donating electrons from ascorbate via DCPIP to plastocyanin. Illumination will then drive electrons through PS I to NADP + ; alternatively NADP + can be replaced by the oxidized form of the non-physiological acceptor methyl viologen ( Fig. 6.12 ).
