During chemiosmosis, protons are pumped into the intermembrane space. Through which specific structure do they flow back to the matrix to synthesize ATP?
Q1. During chemiosmosis, protons are pumped into the intermembrane space. Through which specific structure do they flow back to the matrix to synthesize ATP?
Answer: ATP synthase
Explanation: Protons flow through ATP synthase (F1 particle) to drive ATP synthesis. Cytochromes are responsible for pumping protons out of the matrix.
