Electron Transport Chain

Question	Answer
Electron Transport Chain	This is the last stage of respiration and produces the most ATP. It is a collection of proteins on the inner membrane of mitochondria
Reduced NAD and Reduce FAD release electrons into the chain	These electrons transfer energy to the proteins as they pass through them. The energy is used to pump hydrogen ions out of the inner membrane
The flow of hydrogen ions (protons) down the concentration gradient through ATP synthetase, providing energy to produce ATP	3 ATP are produced from reduced NAD, and 2 ATP are produced from a reduced FAD. So for one glucose molecule, 34 ATPs are produced
Oxygen is the final electron acceptor, it combines with the hydrogen to form water. If oxygen is not present hydrogen cannot pass through so less ATP produced	So altogether 38 molecules of ATP are produced from 1 glucose molecule
