Question

Quizplus · Accepted Answer

The sugar that first binds with carbon dioxide in the Calvin cycle is RuBP (ribulose bisphosphate), which is a five-carbon sugar that combines with CO2 with the help of rubisco enzyme. This reaction leads to the formation of two molecules of 3-PGA (3-phosphoglycerate). Eventually, some of the 3-PGA is converted into G3P (glyceraldehyde 3-phosphate), which is the primary product of the Calvin cycle and a precursor to glucose and other sugars.
