The Calvin Cycle

Ribulose 1,5-Bisphosphate

3 -Phosphoglycerate

3 CO2

3 molecules, 5 carbons each

6 molecules, 3 carbons each

1,3-Bisphosphoglycerate

6 molecules, 3 carbons each

6 ATP → 6 ADP + 6 Pi

Glyceraldehyde 3-Phosphate

6 NADPH → 6 NADP+ + 6 Pi

6 molecules, 3 carbons each

Glyceraldehyde 3-Phosphate

5 molecules, 3 carbons each

G3P (1 molecule)

Triose Phosphate

3 ATP → 3 ADP

Carboxylation

Reduction

Regeneration

Glucose, sucrose, & other sugars

Photosystem ll

Photosystem l

ATP Synthase (Chemiosmosis)

Cytochrome b6f complex

H2O → O2

NADP+ → NADPH

ADP + Pi → ATP

These products used to fuel the Calvin Cycle

In thylakoid membrane

In Stroma

End Products: ATP + NADPH
