Calvin Cycle


1. CO2 enters through the stomata and is picked up by a 5C compound called Ribulose Diphosphate.

2. This forms a 6C sugar which breakes up to give 2 Phosphoglyceric acids. These have 3C each.

3. The H2 produced in the non-cyclic photophosphorylation reduces the acid to Phosphoglyceraldehyde using ATP.

4. The Phosphoglyceraldehyde is then converted to glucose or to more Ribulose Diphosphate.

5. The glucose can be changed into other sugars, starch or brought into the respiration cycle to provide energy.

6. The Ribulose Diphosphate will react with more CO2 and the cycle begins again.
