Expert Answer:
RuBP is a 5-carbon sugar involved in photosynthesis.
The full form of RuBp is Ribulose-1,5-biphosphate. It is an important substrate involved in carbon fixation. The enzyme Rubisco catalyzes RuBP with carbon dioxide in order to synthesize a highly unstable 6-carbon intermediate known as 3-keto-2-carboxyarabinitol 1,5-bisphosphate. This decays virtually instantaneously into two molecules of glycerate 3-phosphate (3PG).
RuBP is both used and created during the Calvin Cycle. It is formed by the phosphorylation of ribulose-5-phosphate by ATP.
