@aaronq i promise this is the last one for me today!

aaronq · Answer

anonymous · Answer

and i think its B.

aaronq · Answer

you're right, but why?

anonymous · Answer

I think it's B. because the electrons' final product is NADPH. Also, ATP is produced by the Chemiosis through ATP Synthase.The ATP synthase works due to the Hydrogen gradient.The H+ gradient is formed because the H+ are being moved to the lumen of the thylakoid membrane with the released energy of electrons.So am I Right?? @aaronq

aaronq · Answer
