Question

Choose the correct answer from the alternatives given.
Which of following is most closely associated with the process of electron transport?

• A. A flattened disk or sac in the chloroplast
• B. A stack of thylakoid membrane structures
• C. The central fluid-filled space of the chloroplast
• D. The cytochrome system in the membranes of the thylakoids

Answer 1

The correct option is D The cytochrome system in the membranes of the thylakoids

The cytochrome b6f complex is distributed evenly throughout thylakoid membranes and that catalyzes the transfer of electrons from plastoquinol to plastocyanin.

So, the correct option is, 'The cytochrome system in the membranes of the thylakoids'.
