The Calvin-Benson Cycle requires?

Question

and what do these products do????

Answer 1

18  ATP, 12 NADPH, and CO2 makes glucose.

Answer 2

This cycle occurs in the stroma and requires 18 ATP's, 12 NADPH's, and CO2.

The Calvin Benson cycle is the opposite of the citric acid cycle in that

the citric acid cycle produces ATP and NADP

and glucose is broken down to make CO2.  

The Calvin Benson cycle uses ATP, NADPH,  and CO2 is used to make glucose.
