[Campbell Biology P.241] Which of the following statements correctly describes the location ... | Practice Question

Which of the following statements correctly describes the location and the direct products of the light reactions of photosynthesis used by the Calvin cycle?

  • A: Occur in the stroma, producing glucose and oxygen.
  • B: Occur in the thylakoids, producing ATP and NADPH.
  • C: Occur in the thylakoids, producing carbon dioxide and water.
  • D: Occur in the stroma, producing ATP and NADPH.

Explanation

The text states, "the thylakoids of the chloroplast are the sites of the light reactions, while the Calvin cycle occurs in the stroma. On the outside of the thylakoids, during the light reactions, molecules of NADP+ and ADP pick up electrons and phosphate, respectively, and NADPH and ATP are then released to the stroma, where they play crucial roles in the Calvin cycle."
