Web34 Chloroplast Extraction and the Hill Reaction where H2O is the electron donor and A is the electron acceptor; water is the only electron donor required. It was further shown that CO2 was not required for this reaction nor was it accumulated in a stable form. Equation 4 is known as the Hill Reaction, and the acceptor A is a Hill Reagent.Subsequent work WebThe 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. He demonstrated that the process by which plants produce oxygen is separate from the process that ...
