Describe some similarities between the electron transport chains in chloroplasts and in mitochondria.
Answer to relevant QuestionsUncouplers of oxidative phosphorylation in mitochondria also uncouple photoelectron transport and ATP synthesis in chloroplasts. Give an explanation for this observation. Why do we describe the path of electrons in photosynthesis as starting in photosystem II and ending in photosystem I? In other words, why is the nomenclature “backward”? How does photosynthesis in C4 plants differ from the process in C3 plants? How is nitrogen fixed (converted from N2 to NH4+)? How is it subsequently assimilated into organic compounds? Does the conversion of IMP to GMP use or produce ATP either directly or indirectly? Justify your answer.
