Study Notes

Mitochondria have highly folded membranes with a large surface area.
The electron transport chain is located in the inner mitochondrial membrane.
The electron transport chain pumps hydrogen ions across the membrane, creating a concentration gradient.
The concentration gradient stores potential energy, similar to water behind a dam.
ATP synthase is a miniature machine that generates ATP using the energy from the concentration gradient.
Cyanide blocks the passage of electrons to oxygen, preventing ATP production.
The electron transport chain is made up of protein complexes and electron carriers.
NADH and FADH2 transfer electrons to the electron transport chain.
Oxygen pulls electrons down the transport chain.
ATP synthase attaches phosphate groups to ADP molecules to generate ATP.
