The first reaction of this cycle produces 3-phosph
The first reaction of this cycle produces 3-phosphoroglycerate, which is converted into 1,3 bisphos-phoroglycerate, then 3-phosphoglyceraldehyde, then ribulose 5-phosphate, and finally back into ribulose 1,5  bisphosphate, more commonly known as RuBP. The enzyme it depends on is generally recognized as the most common protein on earth, RubisCO. Producing the 1967 Nobel Prize in Chemistry for its eponymous discoverer, for ten points, what is this cycle, also known as the "dark cycle", by which plants produce glucose?
