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...

Which of the following best describes what occurs during the electron transport chain? The diffusion of H+s provides the energy needed to make electrons move through the electron transport chain. Once the electrons reach oxygen, ATP is produced. O An H+ gradient is used to place oxygen at the end of the electron transport chain. The oxygen then pulls electrons towards it, which results in the synthesis of ATP. The energy of moving electrons is used to generate a proton...

What happens along an electron transport chain?
What happens along an electron transport chain? Electrons are passed from a reducing agent to an oxidizing agent, releasing free energy at each step. Electrons are passed from molecule to molecule, gaining potential energy at each step. O Electrons store energy that can be used to break down sugar molecules. O Protons are pumped through ATP synthase, making ATP.
