Question

Quizplus · Accepted Answer

All three options are part of the photosynthetic electron transport chain between photosystems I and II. Plastocyanin is a small copper-containing protein that transfers electrons from the cytochrome b6f complex to photosystem I. Plastoquinone is a lipid-soluble molecule that shuttles electrons between photosystem II and the cytochrome b6f complex. The cytochrome b6f complex contains both cytochrome b and cytochrome f, which shuttle electrons between the two photosystems and generate a proton gradient across the thylakoid membrane.
