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

At the end of the Kreb's cycle, where is most of the energy from the original glucose stored?

• in CO₂
• in ATP
• in NADH
• in pyruvate

• glucose and oxygen
• water and glucose
