The Calvin Cycle
1. carbon dioxide from the atmosphere diffuses into the leaf through stomata and dissolves in water around the walls of the mesophyll cells. It then diffuses through the plasma membrane, cytoplasm and chloroplast membranes into the stroma of the chloroplasts.
2. In the stroma, carbon dioxide comobines with the 5-carbon compound ribulose biphosphate (RuBP) using an enzyme
3.The combination of CO2 and RuBP produces two molecules of 3-carbon gylcerate 3-phosphate (GP)
4.ATP and NADP from the light-dependant reaction are used to recude the activated gylcerate 3-phosphate to triose phosphate (TP)
5. The NADP is reformed and goes back to the light-dependant reaction to be reduced again by accepting more hydrogen.
