Explanation:
a. Photosystem II Light shining on pigments energizes electrons that come from water.
b. Electron transport chain: High energy electrons move down the chain, which pumps H+ ions to inside of the thylakoid
c. Photosystem I: electrons are reenergized with more light.
d. Electron Transport: the reenergized electrons are transferred to NADP+ to make NADPH
