In the calvin cycle, triose phosphate is formed during
Open in App
Solution
The correct option is B reduction stage
Calvin cycle includes three stages - carboxylation stage, reduction stage and regeneration stage.
During the carboxylation stage, CO2 combines with RuBP (primary acceptor of carbon dioxide) and forms 3-PGA (3-phosphoglycerate). 3-PGA is the first stable product formed during the calvin cycle.
Carboxylation is followed by a reduction stage during which the 3-PGA undergoes reduction to form glyceraldehyde 3-phosphate which is also known as triose phosphate. Hence, triose phosphate is formed during the reduction stage.
Some molecules of triose phosphate are recycled to regenerate RuBP, the primary acceptor molecule of CO2.
Some molecules of triose phosphate are utilised in the synthesis of glucose.
