Question

Which process occurs last in the Calvin cycle ?

A. splitting of water
B. carbon fixation
C. formation of an "excited" electron
D. formation of NADPH

Answer 1

Your answer is B. carbon fixation
I know the answer because I took the same test and that is the answer

Answer 2

The correct anwser is D because the reactions of the Calvin cycle add carbon (from carbon dioxide in the atmosphere) to a simple five-carbon molecule called RuBP. These reactions use chemical energy from NADPH and ATP that were produced in the light reactions. The final product of the Calvin cycle is glucose.
