1)In the Calvin cycle Determine: How many molecules of CO2 must be fixed to form a molecule of glucose? How many molecules of ATP are needed to make one Glyceraldehyde 3-phosphate? How many NADPH? How many NADPH would be needed to make one glucose? 

(could you explain in one turn in the calvin cycle what it creates, rather than the full summary of the 3 turns. thats why i am having difficulty answering these questions^)
