Hill reaction - WikipediaKnow More

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 photosynthesisThe discovery of the reaction, by Robin Hill in 1937, demonstrated that the process by which plants produce oxygen is separate from the process that converts carbon dioxide to sugars
