According to the chemiosmotic hypothesis, where is the highest concentration of protons maintained to drive ATP synthesis during the light-dependent reactions?
Q1. According to the chemiosmotic hypothesis, where is the highest concentration of protons maintained to drive ATP synthesis during the light-dependent reactions?
Answer: Thylakoid lumen
Explanation: Protons are pumped into the thylakoid lumen to create a gradient; the stroma has a lower proton concentration during this process.
