During non-cyclic photophosphorylation, how does NADP+ become NADPH?
Specifically during non-cyclic photophosphorylation, I know that the chlorophyll already has preexisting NADP+ molecules, water is broken to release 2 hydrogen atoms and 1 oxygen atom (two water molecules break down to form gaseous oxygen that we breath), those 2 hydrogen atoms get sent down and along the Electron Transport Chain via solar energy and then I believe one goes to a protein called ATP synthase and the other goes to photostem 1. After photostem 1 that hydrogen binds to free floating NADP+ molecules to from charged NADPH. This should be the gist of it all but I would also recommend listening to someone else's input as well.
