Question

In stage 2 of photossynthesis, NADP+ becomes NADPH by adding an H+. Where does the H+ come from?

Answer 1

Enzymes break up water or H2O into electrons, H+ ions, & oxygen atoms. Electrons replace the "highenergy" electrons that were lost in the electron transport chain.Oxygen is released and the H+ ions are also released. - So the first one would be A. splitting of water or H2O

and the second one is B :)
