Question

rubp, rubisco and carbon dioxide have a reaction transformation during stage one of the calvin cycle which results in the creation of _______, which is a three - carbon compound.
atp
3 - pga
nadph
glucose

Explanation:

In the first stage of the Calvin cycle, RuBP (ribulose - 1,5 - bisphosphate) combines with \(CO_2\) in the presence of RuBisCo (ribulose - 1,5 - bisphosphate carboxylase/oxygenase). This reaction forms two molecules of 3 - PGA (3 - phosphoglycerate), which is a three - carbon compound. ATP is an energy - carrying molecule, NADPH is a reducing agent, and glucose is a product of later stages of the Calvin cycle (and is a six - carbon sugar), so they are not the product of this specific reaction.

Answer:

B. 3 - PGA
