NEET Botany (general) MCQ Question
Which of the following statements about the process of photosynthesis in higher plants is correct?
Electrons in photosystem I are excited by red light and help reduce NADP+ to NADPH.
NADP reductase functions in the mesophyll cells to facilitate the conversion of NADP+ to NADPH.
Protons are released into the stroma during the electron transport in photosystem II.
The primary acceptor of electrons in photosystem II is involved in producing ATP directly.
Correct Answer
Detailed Explanation
Statement A is correct as it describes the role of electrons in photosystem I, which are excited by red light and contribute to the reduction of NADP+ to NADPH. Statement B is incorrect because NADP reductase is located on the stroma side, not in mesophyll cells. Statement C is false as protons are released into the lumen, not the stroma. Statement D is misleading since the primary acceptor does not produce ATP directly.
