In the chloroplast, cytochrome b₆f is an important complex in the photosynthetic electron transport chain because it accepts electrons from photosystem II and donates them to photosystem I. Another vital function of cytochrome b₆f is that, during its reduction-oxidation cycle, it moves _____ from the _____. A)protons; stroma into the thylakoid lumen B)electrons; stroma into the thylakoid lumen C)protons; thylakoid lumen into the stroma D)electrons; thylakoid lumen into the stroma

Question

Quizplus · Accepted Answer

Cytochrome b6f complex functions in the photosynthetic electron transport chain by pumping protons from the stroma into the thylakoid lumen, contributing to the proton gradient used for ATP synthesis.
