1. which of the following happens in the light-dependent reactions of photosynthesis?
a. water molecules are split.
b. energy is captured by pigments.
c. atp is produced by atp synthase.
d. all of the above are correct.
2. the energy-absorbing molecules of plant cells are located in the
a. electron transport chain
b. chemiosmotic gradient
c. stroma
d. thylakoids

Well im not sure but this might helps... 1. light energy is absorbed by electrons in pigments and water molecules are split into H+ ions, oxygen, and electrons 2. high energy electrons move down the electron transport chain, where energy from electrons is used to pump h+ ions into thylakoid space 3. at end of chain, NADP+ molecules pick up the high energy electrons along with H+ ions to become NADPH 4. H+ ions in the thylakoid space pass thru apt synthase in the thylakoid membrane, causing the ATP synthase base to rotate and produce ATP
