For 10 points, name this reaction cycle that occurs in the stroma and produces sugars from carbon dioxide.
Its last two phases are reduction and regeneration. Important enzymes in these steps include aldolase, transketolase, and sedoheptulose bisphosphatase. C4 plants use PEP carboxylase to form oxaloacetate before beginning these reactions, allowing them to increase productivity by carboxylating more often than can C3 plants. NADPH is oxidized when it donates an electron to form G3P, which can be converted to glucose. However, five out of every six G3Ps are used to regenerate RuBP, which is attached to CO2 by Rubisco in the first step.
