I am a Rohit MSc student in microbiology. I will send a Calvin cycle C3.1. C3 Pathway (Calvin Cycle) 2. The Calvin Cycle (C3) - It occurs in the stroma - NADPH and ATP molecules are rapidly being provided to the metabolic pathways in the stroma. - Therefore, ATP and NADPH formed during the Light Dependent reaction are used in the stroma to fuel the Calvin Cycle reactions. 3. - The Calvin Cycle consists of a series of reactions that reduce carbon dioxide to produce the carbohydrate glyceraldehyde-3-phosphate. • Carbon Fixation • Reduction • Regeneration 4. - Carbon Fixation - In this step, carbon dioxide is attached to Ribulose 1,5-bisphosphate resulting in six-carbon molecule that splits into two three carbon molecules. 5. - Reduction - This step is the sequence of reactions using ele- from NADPH and some of the ATP to reduce carbon dioxide. 6. - Regeneration - In the final step, ribulose 1,5-bisphosphate is regenerated. For every three turns of the cycle, five molecules of glyceraldehyde-3-phosphate are used to re-form 3 molecules of ribulose 1,5-biphosphate. 7. RuBisco 8. THANK YOU
