Where does the splitting of the water molecule take place in the chloroplast?

Step-by-step solution

Since splitting of the water molecule takes place on the inner side of the membrane , the protons or hydrogen ions that are produced by the splitting of water accumulate within the lumen of the thylakoids. As electrons move through the photosystems, protons are transported across the membrane. This happens because the primary accepter of electron which is located towards the outer side of the membrane transfers its electron not to an electron carrier but to an H carrier. Hence, this molecule removes a proton from t
