Class 11 Botany simulations · Respiration in Plants

Electron transport and ATP synthase

Inside the mitochondrion, electrons flow along the inner membrane and pump protons; ATP synthase uses the flow back to make ATP.

Open the simulation

What to notice

Oxygen is the final electron acceptor; without it the chain stops and so does most ATP production.

Key relation

NADH → I ; FADH₂ → II ; both → ubiquinone → III → cyt c → IV → O₂ + 4H⁺ + 4e⁻ → 2H₂O

Try this

Lower the oxygen supply to zero.

What you can change

• Oxygen supply: 0 to 100 %
• NADH supply: 0 to 100 %
