quantum requirement of photosynthesis

…As a result of evolution based on bacterial photosynthesis, green plant photosynthesis, which uses water, which is abundant on Earth, as a hydrogen donor, appeared about 1 billion years ago, leading to the appearance of O 2 on Earth. The number of CO 2 molecules fixed or O 2 molecules generated by one light quantum is called the quantum yield of photosynthesis, and the reciprocal of this is called the quantum requirement of photosynthesis. OH Warburg once advocated a value of 4 (four-light quantum theory) for the required quantum number, but a value of 8 to 10 is now generally accepted. …
