The Hill reaction, also known as the Hill photosynthetic oxygen evolution, is a process that occurs during photosynthesis in green plants, algae, and cyanobacteria. It was first described by British biochemist David Keilin in the 1920s and later refined by British biochemist and Nobel laureate Melvin Calvin in the 1950s.
