Energy from the electrons is used by the molecules in the electron transport chain to transport positive H ions from the stroma into the inner thylakoid space.Is this molecule NADP?and where do they get the positive H ion from?Thanks in advance!
Splitting water releases two electrons and two protons. The electrons are used to transport the protons from the stroma to the thylakoid space. The molecules that transport protons are specific cytochromes in the electron transport chain. This proton gradient is used to synthesize ATP using chemiosmosis, and the electrons are eventually passed to NADP+ reductase, which uses the two protons to synthesize 2 NADPH molecules. The NADPH enters the Calvin cycle to reduce CO2 to sugars.
Aptitude couldn't have said it anymore perfect. And take a look at the figures for a graphical illustration (assuming you have a textbook). The figures always helped my understanding.
