In chloroplasts, the light reactions power the creation of ATP via chemiosmosis. In relation to this process, which of the following is true? a) ATP synthase breaks ATP down into ADP, creating energy to fuel chemiosmosis. b) Oxygen is used as a source of electrons to replace those lost in photosystem II. c) Chemiosmosis during the light reactions is also used in the reduction of NADPH and FADH2. d) As excited electrons fall back down to a lower energy state, they create a proton gradient that is used to fuel the phosphorylation of ADP.
