Answer:
ATP and NADPH are used to energy for the production of the Calvin cycle. Once their energy is released, they revert back to ADP and NADP+ and can be reused again.
Explanation:
ATP and NADPH are energy carriers that can be used to power chemical reactions. Once they have energized cellular processes, they become their 'low energy' form of ADP and NADP+. Later, they can reform ATP and NADPH to power more reactions
