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. WebThe Hill reaction gives evidence that the light-dependent and light- independent stages take place in various parts within the cell. The liberation of oxygen requires light as Hill’s experiment suggests and thus can be described as the light dependent reaction of photosynthesis. ...
