Q. I. The electrons that carriers photophosphorylation are located in the thylakoid membrane II. During photophosphorylation, the chloroplast stroma becomes more acidic than the interior of thylakoid membrane III. Protons diffuses through the protein channels which are ATP synthetase molecules IV. ATP is formed from ADP + Pi on the stroma side of the thylakoid in the chloroplast V. During photophosphorylation, water ionises to form $H^{+}$, yielding electrons to PS-II Which of the following statement are false?

A) I and II
B) III and IV
C) IV and V
D) Only II
Explanation

During phosphorylation, the chloroplast stroma is less acidic than the interior of thylakoid membrane because accumulation of protons during electron transport chain occurs in the lumen of thylakoid
