  1. Question 1

    Q1. In the thylakoid membrane, a high concentration of protons is established in the lumen. Which protein complex utilizes this gradient to produce energy?

    • A) ATP synthase
    • B) Cytochrome complex
    • C) Plastoquinone
    • D) Ferredoxin

    Answer: ATP synthase

    Explanation: ATP synthase uses the proton motive force for phosphorylation; cytochromes are tempting but they only transport electrons, not protons.
