Answer:
D) Passing of electrons from Photosystem I to electron transport chain.
Explanation:
The NADPH is generated in the thylakoid membrane first in order to energize the second stage of photosynthesis (Calvin Cycle). Calvin Cycle takes place in the stroma, so that choice is out. Choices A, B, and C are in cellular respiration, and NADPH is not made in that process, so that leaves choice D.
