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 WebNov 21, 2013 · Series 3- Lab 9 Measuring Photosynthetic Rate Using the Hill Reaction. In today's lab, you will measure the rate of electron transport in thylakoid membranes isolated from spinach chloroplasts using a procedure called the Hill Reaction. This procedure will allow you to measure the rate of oxygen evolution, and thus the rate of photosynthesis ...

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.
