Answer:
Ribulose bisphosphate (RuBP)
Step-by-step explanation:
Hello,
Calvin cycle is a biochemical process that accounts for the carbohydrate production done by the plants. It is divided in three stages fixation (enzyme RuBisCO incorporates carbon dioxide into an organic molecule), reduction, and regeneration in which Ribulose bisphosphate (RuBP), the molecule that starts the cycle, is regenerated so that the cycle can continue.
Best regards.
