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. Webaccepted by NADP. This reaction was discovered in 1938 by Robin Hill and thus is often called the Hill reaction. Dehydrogenase catalyses this reaction. When a redox indicator dye is present, such as DCPIP ( which turns from blue to colourless when it is reduced), electrons are accepted by this instead. Equipment
