(Shmoop, 2015)

PHASE 1

  • An atmospheric carbon (meaning a random carbon from the atmosphere) comes in and with the help of the slow enzyme RUBISCO, the combo of the carbon and RuBP makes PGA

 

PHASE 2

  • Now it's time to downgrade PGA into G3P:

    • 6 ATPs phosphorylate (gives a phosphate) to PGA making it now 1,3 BPG

    • 6 NADPH reduce (give electrons) to 1,3 BPG and now we have 6 G3P....

    • ....until 1 leaves to go make some sugar

 

PHASE 3

  • The combo of 5 G3P and 3 ATP regenerates 3 RuBP to then continue the cycle
