Question

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

Answer 1

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
