WebDCPIP is a coloured dye which also accepts electrons during light reactions and loses colour as it gets reduced to DCPIPH 2. This can be used to estimate the rate of electron transport as the faster the dye will lose colour, the faster the rate of the electron transport occurs thus the faster the rate of photosynthesis. WebHill reaction. Plant cells with visible chloroplasts (from a moss, Plagiomnium affine) The Hill reaction is the light-driven transfer of electrons from water to Hill reagents (non-physiological oxidants) in a direction against the chemical potential gradient as part of photosynthesis. Robin Hill discovered the reaction in 1937.
