9.4: During oxidative phosphorylation, chemiosmosis couples electron transport to ATP synthesis. The electron transport chain and the electron flow down the chain is coupled to ATP synthesis. The electron transport chain is a collection of molecules embedded in the inner membrane of the mitochondrion in eukaryotic cells. Most components of the chain are proteins. Tightly bound to these proteins are prosthetic groups, nonprotein components essential for the catalytic functions of certain enzymes. During the e- transport along the chain, e- carriers alternate between reduced and oxidized states as they accept and donate e-. Each component of the chain becomes reduced when it accepts e- from its ?uphill? neighbor, which has

Need Notes?
While we strive to provide the most comprehensive notes for as many high school textbooks as possible, there are certainly going to be some that we miss. Drop us a note and let us know which textbooks you need. Be sure to include which edition of the textbook you are using! If we see enough demand, we'll do whatever we can to get those notes up on the site for you!
