⦁ Electron Transport Chain:

Question

⦁ How many ATP are produced? ____
⦁ Other notes about this stage:

Answer 1

- The electron transport chain is the final stage of cellular respiration.
- It takes place in the inner membrane of the mitochondria.
- During this stage, electrons from NADH and FADH2 are transferred through a series of protein complexes.
- As electrons pass through these protein complexes, energy is released and used to pump protons across the inner membrane, creating a proton gradient.
- The protons then flow back through ATP synthase, driving the synthesis of ATP.
- For every pair of electrons passing through the electron transport chain, approximately 3 ATP molecules are produced.
- The exact number of ATP produced can vary, but on average, around 28 to 32 ATP molecules are generated during the electron transport chain stage of cellular respiration.
