Document Content and Description Below

Electron Transport Chain Lab (66 pts.) Go to this website: Cellular Respiration (Electron Transport Chain) 3:50 Answer these questions. You will find the answers in the video. 1. What is the elect ... ron transport chain? - The electron transport chain is a series of protein complexes embedded in the mitochondrial membrane. 2. What happens to electron, captured from donor molecules, in the electron transport chain? - Electrons captured from donor molecules are transferred through these complexes. 3. What reaction is coupled with this transfer of electrons? - Coupled with this transfer is the pumping of hydrogen ions. 4. What does this pumping generate? - Generates the gradient used by the ATP synthase complex to synthesize ATP. 5. What complexes are found in the electron transport chain? There are four. Pause the video so you can write down each name or type them into your assignment document. Put these terms on an index card too! - NADH Dehydrogenase - Cytochrome b-c1 - Cytochrome Oxidase - ATP Synthase 6. In addition to the complexes, what two energy carriers are in the electron transport chain? - Ubiquinone and Cytochrome c 7. And, what are the other components in the electron transport chain? There are eight [Show More]
