http://faculty.buffalostate.edu/wadswogj/courses/BIO211%20Page/lectures/lab%20pdf 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.

WebWe are interested in the ability of chlorophyll-a in the reaction center of PSII 680 to split water and liberate free molecular oxygen in the process.
