WebThe equation below represents the photosynthesis reaction: The purpose of this experiment is to test whether factors such as light intensity and level of Carbon dioxide, will affect the rate of photosynthesis, which are the two most important variables in the photosynthesis process. This was demonstrated by Robert Hill in 1938, known as “The ...

The Hill Reaction: A Key Step In 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. WebThe reaction in green plants follows: light. CO2 + H2O. (CH2O) + O2. Shown above, CH2O stands for carbohydrate. In green plants, photosynthesis involves a series. of oxidation-reduction reactions in which water is the electron donor and oxygen is released. (Figure 1). In the 1930s, Robin Hill investigated electron. grace counseling littleton
