- light in- dependent reaction Calvin cycle
- 1: CO2 combines with 5C RuBP, this is fixing and is catalysed by RuBP carboxylase/ RUBISCO
- 2: this breaks down to for 2 x Glycerate 3 Phosphate ( GP)
- 3: the GP is then reduced using NADPH and ATP from light dependent reactions
- 4: this forms triose phosphate 3C (TP)
- 5: GP can also be used to form amino acids and fatty acids
- 6: most of the TP is used to re-generate RuBP which also requires ATP
- 7: some TP is used to make hexose sugars e.g. glucose and some polysaccharides
- 8: some TP is used to make glycerol which combines with fatty acids from GP to make lipids
