During carbon fixation (phase 1), CO₂ is attached to RuBP (ribulose bisphosphate) by the enzyme **ribulose bisphosphate carboxylase/oxygenase**, commonly known as **RuBisCO**. As a result of this reaction, a **6-carbon intermediate** is formed, which quickly splits into two molecules of **3-phosphoglycerate (3-PGA)**.
In phase 2, the reduction phase, each molecule of **3-phosphoglycerate** is reduced to form **glyceraldehyde-3-phosphate (G3P)**. This process requires energy from **ATP** and **electrons (in the form of NADPH)** from NADPH.
In phase 2, the reduction phase, each molecule of **3-phosphoglycerate** is reduced to form **glyceraldehyde-3-phosphate (G3P)**. This process requires energy from **ATP** and **electrons (in the form of NADPH)** from NADPH.
