The second stage of the Calvin cycle, also known as the reduction stage, involves the use of ATP and NADPH to convert CO2 into carbohydrates. These energy-rich molecules are produced during the light-dependent reactions of photosynthesis and are used in the Calvin cycle to build sugars. Thus, the correct characteristic of the second stage of the Calvin cycle is that it uses ATP and NADPH.
