| Calvin cycle, animation. The Calvin cycle is the sequence of light-independent reactions that take place during photosynthesis. Photosynthesis is the process plants use to synthesise carbohydrates from carbon dioxide and water using sunlight. The three stages of the Calvin cycle are shown. During the first phase, carbon fixation, carbon dioxide (CO2) is added to the five-carbon sugar ribulose bisphosphate to form a transient six-carbon sugar, which splits into two molecules of the three-carbon sugar 3-phosphoglycerate with the addition of water (H2O). During the second phase, reduction, 3-phosphoglycerate is converted to phosphoglyceraldehyde. Two molecules of this can combine to form one molecule of glucose. In phase three, regeneration, some of the phosphoglyceraldehyde is converted back to ribulose bisphosphate, which can be used to start the cycle again. | |
