Dark Reaction (Calvin Cycle) Notes

Dark Reaction / Light Independent Reaction / Calvin Cycle

• Happens in the stroma (the area outside the grana, outside the thylakoid).
• Does not need light; relies on different molecules.

Connection to Light Dependent Reaction

• NADPH and ATP produced in the light-dependent reaction are used in the Calvin cycle.
• ADP (from ATP usage) and NADP+ (from NADPH usage) are sent back to the light-dependent reaction to be
