not bisphosphate. BIPHOSPHATE.

I'm studying the same thing right now...and our text is also relating this enzyme to photosynthesis (specifically the Calvin Cycle). It is a 5-carbon atom (RuDP) that joins with CO2 from the air to form a 6-carbon compound. During the Calvin Cycle, there is continuous regeneration of RuDP which = continuous fixation of carbon.

Oh I was just reading about that a few minutes ago and I was questioning that too for the chapter on photosynthesis.
I think that an enzyme [Ribulose bitphosphate] during the calvin/c3 photosynthesis cycle catalyzes the merging of CO2 and RuBP.
Then during regeneration 6ATP are used to convert 10 G3P to 6RuBP. All of this seems really similar to the bisphosphate and the internet results redirect me to it aswell. Perhaps your teacher miswrote it?

"Biphosphate" is in incorrect term and not one that is used by chemists and shouldn't be used in any textbook or by instructors. The term "bisphosphate" like in ribulose bisphoshate means that two phosphate groups are bound to the ribulose molecule in two different places. "Diphosphate" means that two phosphate groups are linked to each other by a phosphoanhydride bond.
