What is it's role in dark reactions of Photosynthesis??

RuBP is short for Ribulose 1,5 Biphosphate. It is a five carbon sugar with two phosphate groups attached. It can exist in open chain form, or in ring form. Its production is catalyzed by Ribulose Bis 1,5 Phospate Carboxylase (RuBisCo).
Essential to photosynthesis, RuBP as a 5 carbon compound will attach to carbon dioxide taken in by a plant. At this point the inorganic carbon has become incorporated into an organic compound. This term is called "carbon fixation". Every photosynthesizing plant has RuBP within it, as well as RuBisCO. Once the carbon has been fixed, the compound can enter the Calvin Cycle.

full form of RuBP is ribulose 1,5 biphosphate ....It's purpose is in the dark reaction. It is formed by taking a phosphate, coming from the splitting of ATP, and joining it with RuP, changing RuP (ribulose phospate) into RuBP. RuBP is then able to join with CO2 and form an unstable 6C molecule which is the basis for the dark reaction.
