Read the following statements regarding the development of a proton gradient in chloroplasts during the light reaction: (A) Splitting of the water molecule takes place on the inner side of the membrane, accumulating protons within the lumen. (B) As electrons move through the photosystems, protons are transported from the stroma to the lumen. (C) NADP reductase enzyme is located on the stroma side of the membrane and

Step-by-step solution

Statements (A), (B), and (C) correctly describe the mechanisms that contribute to the development of a proton gradient across the thylakoid membrane. Statement (A) is correct because the water-splitting complex is located on the inner side of the thylakoid membrane, releasing protons directly into the lumen. Statement (B) is correct as the primary electron acceptor transfers its electron to a hydrogen carrier, which removes a proton from the stroma and releases it into the lumen during electron transport.
