Describe the Calvin Cycle and where it occurs. Scroll down to see answer.

Occurs in the dark reaction (stroma).
Starts with carbon dioxide that attaches to RuBP (5 carbons) and forms an unstable 6 carbon molecule.
The 6 carbon molecule falls apart, forming 2 PGA (3 carbons each). An ATP joins them, followed by an NADPH, which drops off a hydrogen, and goes back to the light reaction. The hydrogen attaches to the PGA and forms PGAL, which forms glucose or RuBP (with 5 carbons).
6 CO2 + 6 H2O =Light and Chlorophyll=> C6H12O6 + 6O2
