What happens to NADPH and ATP after they are used in the Calvin Cycle?

• they recycle back to the light reactions
• they are used to make G3P

What happens to the remaining G3P molecules in the last step of the dark reactions?

• They are used to make glucose.
• They are reshuffled to make CO₂ by adding ATP.
