Question

Quizplus · Accepted Answer

RuBP (ribulose-1,5-bisphosphate) is the compound required for the carboxylation step of the Calvin cycle. This step involves the attachment of carbon dioxide to RuBP, resulting in the formation of two molecules of 3-phosphoglycerate (3-PGA). ATP and NADPH are both required for later steps in the Calvin cycle, but not for the initial carboxylation step.
