In the thylakoid membrane, a high concentration of protons is established in the lumen. Which protein complex utilizes this gradient to produce energy?
Q1. In the thylakoid membrane, a high concentration of protons is established in the lumen. Which protein complex utilizes this gradient to produce energy?
Answer: ATP synthase
Explanation: ATP synthase uses the proton motive force for phosphorylation; cytochromes are tempting but they only transport electrons, not protons.
