| Question | Answer |
| Electron Transport chain | found on the inner membrane of the mitochondria and consists of a series of carrier protiens |
| Step one | NADH and FADH2 from glycolic and citric acid pathways release high energy electrons and pass them to the electron transport chain |
| Step 2 | begin in a high energy state and as they flow along the chain of electron acceptors they release energy |
| What is this energy used for? | The energy is used to pump hydrogen ions across the membrane from the matrix side to the intermediate space, where there is a higher concentration of hydrogen ions |
| Step 3 | The return flow of hydrogen ions to the matrix makes ATP synthase to synthesize ATP |
| Step 4 | At the end of the electron chain the electrons combine with oxygen and at the same time oxygen combines with a pair of hydrogen ions to form water |
| Final Electron Accepter | Oxygen |
