Cellular respiration: The Electron Transport Chain The breakdown of glucose ends during the Krebs cydle; however, it is important to note that the energy previously contained in glucose is mostly stored in NADH and FADHz. In the last step of celular respiration, the high-energy electrons within NADH and FADH2 are passed within a set of proteins found in the inner membrane of the mitochondrion, collectively known as the electron transport chain. The electrons provide the energy to create ATP, which...
