1. Carbon dioxide from the atmosphere diffuses into the leaf through stomata and dissolves in water, it then diffuses through the cell surface membrane, cytoplasm and chloroplast membranes into the stroma of the chloroplast.
2. Carbon dioxide reacts with RuBP, this reaction is catalysed by the enzyme RUBISCO
3. The reaction between CO2 and RuBP produces two molecules of GP (3 carbon molecule).
4. Reduced NADP and ATP from the light dependent reaction are used to reduce GP to TP using the ATP
5. NADP is reformed and goes back to the light-dependent reaction
6. Some TP molecules are converted into organic substances such as glucose, starch, lipids and amino acids.
7. Most TP molecules are used to reform RuBP using ATP from the light dependent reaction
