The first event in the Calvin cycle is the attachment of carbon dioxide to the five-carbon RuBP molecule,which forms a six-carbon molecule that breaks down into two 3PG molecules.

Question

Quizplus · Accepted Answer

The Calvin cycle begins with carbon fixation, where CO2 is attached to RuBP, forming an unstable six-carbon compound that splits into two molecules of 3-phosphoglycerate (3PG).
