The Calvin Cycle Step 1 Carbon Fixation
The Calvin Cycle Step 1 Carbon Fixation
3 Molecules of CO2 enter the cycle
3 Molecules of CO2 enter the cycle
Each join a 5 Carbon RUBP and Immediately SPLIT--->Into
6 3 Carbon PGA

Step 2 PGAL SynthesisStep 2 PGAL Synthesis
The 6 Molecules of PGA Change into 6 Molecules of PGAL
ATP is used for this step for energyATP---->ADP + P + energyNADPH is also used for H+ and e--NADPH---> NADP+ + H+ + 2e-

1 PGAL is used to make Glucose (2 are needed for 1 Glucose)
The remaining 5 are used to make RUBP
1 PGAL is used to make Glucose (2 are needed for 1 Glucose)
The remaining 5 are used to make RUBP
Step 3 Regeneration of RUBP
Step 3 Regeneration of RUBP
RUBP is regenerated by re-arranging the remaining 5 PGALS
RUBP is regenerated by re-arranging the remaining 5 PGALS
