  4. During light-dependent reactions, light energy is converted to chemical potential energy through the process of chemiosmosis in the chloroplasts. Which of the following statement about this process is false - (I). The electron carriers of phosphorylation are located in the thylakoid (II). During phosphorylation, the chloroplast stroma becomes more acidic than the interior of thylakoid membrane (III). Protons diffuse 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 phosphorylation, water ionizes to form H+ +2OH- yielding an e- to PSII
