Study Notes
Calvin Cycle Overview
- The primary product of the Calvin cycle is glucose (G3P).
Calvin Cycle Reactions
- NADPH is used to reduce CO2 into glucose, providing energy for carbon fixation.
Carbon Fixation
- The enzyme RuBisCO (Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase) is responsible for fixing carbon dioxide in the Calvin cycle.
Initial Fixation
- CO2 is initially fixed into a three-carbon molecule called 3-phosphoglycerate (3-PGA) during the Calvin cycle.
Purpose of Calvin Cycle
- The purpose of the Calvin cycle in photosynthesis is to produce glucose (energy) for the plant to grow and develop.
Cycle Completion
- RuBP (Ribulose-1,5-Bisphosphate) is regenerated at the end of the Calvin cycle, allowing the cycle to repeat.
