During chemiosmosis

• H+ ions serve as the final electron acceptor
• a concentration gradient is generated when H+ ions are passively transported from the matrix to the intermembrane space of the mitochondrion
• energy is released as H+ ions move freely across the mitochondrial membrane
• ATP is synthesized when H+ ions move through a channel in ATP synthase
