Hi to everyone,
I am righting here for a first time and I would like to ask You a question which may sound a little bit of.. stupid maybe but I can't find information anywhere about it...absolutely anywhere...
Ok, through the light phase of photosynthesis some events as water photolysis, proton pumping, reduction and phosphorylation occur.So, when the water molecule is photolysed 2 protons and 2 electrons are released \and oxygen too\.At some point of time those particles would reach NAD+ by reducing it...But my question is:
For the reduction of NAD+ 2 electrons and 1 proton are needed...So..what happens with the other proton?
I know that the protons are transferred between the lumen and the stroma through the process but at some point they finally would reach NAD+..But with every splitting they would increase their number by 1 and I suppose that such event probably would lead to a harmful situation for the chloroplast...
This question makes me crazy...am I missing something..is there another acceptor or something?Please, help.
