During chemiosmosis in chloroplasts, a high concentration of protons (H+) is established in which specific compartment to drive ATP synthesis?
Q1. During chemiosmosis in chloroplasts, a high concentration of protons (H+) is established in which specific compartment to drive ATP synthesis?
Answer: Thylakoid lumen
Explanation: Protons are pumped into the thylakoid lumen during light reactions, creating a low pH (acidic) environment compared to the stroma.
