Study Notes
Electron Transport Chain
- Oxygen is the ultimate 'electron sink' that drives the oxidation reactions in the electron transport chain.
- The purpose of the Proton Motive Force (PMF) generated by the electron transport chain is to drive ATP synthesis.
Mitochondria Structure
- The inner mitochondrial membrane is impermeable to most molecules except those with specific transporters or channels.
- The outer mitochondrial membrane is permeable to most small molecules via porins.
Electron Transport and ATP Synthesis
- High-energy electrons are carried by electron carriers (such as NADH and FADH2) to generate a proton (H+) gradient across the inner mitochondrial membrane.
- The ultimate function of the Electron Transport Chain (ETC) is to generate a proton gradient that drives ATP synthesis.
- The main function of the inner mitochondrial membrane is to facilitate the electron transport chain and ATP synthesis.
- The synthesis of ATP in the mitochondria is driven by the proton motive force generated by the electron transport chain.
Oxygen's Role
- Molecular O2 is the final electron acceptor, which receives the electrons at the end of the electron transport chain.
