- How does the electron transport chain and the process of chemiosmosis work to form ATP?arrow_forwardA proton gradient is created during the electron transport chain using the energy released from the oxidation of NADH and FADH2. The protons then cross the membrane through ATP synthase down their electrochemical gradient, and ATP is produced. This is an example of A) energy coupling B) cotransport C) allosteric regulation.arrow_forwardPresent the Cellular organization of the electron transport chain ?arrow_forward
- Why are electron carriers (NAD+/NADH and FAD/FADH2) so important in the process of cellular respiration? A)NADH and FADH2 are major components of the ETC, so without them, there would be no ETC in the cell. B)They deliver electrons to the ETC, which in turn sets up chemiosmosis, where most of the ATP is generated. C)They separate the electrons from the protons so that the protons can be moved out of the mitochondrion. D)The electrons that they carry are able to directly phosphorylate ADP in order to generate the bulk of ATP in the cell. E) They transport protons across the mitochondrial membrane. 14.arrow_forwardWhat are the ultimate products of the electron-transport chain?arrow_forwardWhy would lack of oxygen completely inhibit the Krebs cycle and the electron transport chain but not glycolysis?arrow_forward
- What is the direct mechanism of ATP synthesis during the electron transport phase of cellular respiration? (what is the potential energy source that drives ATP production?) b) Why is oxygen needed for this phase? c) What is the role of ATP synthasearrow_forwardWhat happens if there is no oxygen in the electron transport chain?arrow_forwardWhich process is directly affected by DCCD, electron transfer or ATP synthesis?arrow_forward
- Energy is required to reverse the flow of the electron transport chain. Why would this be so?arrow_forwardHow is the energy of electron transfer is coupled to protein pumping and ATP synthesis?arrow_forwardAerobic respiration takes place in three stages: transition, Krebs cycle, and electron transport. What is each stage called and where in the mitochondrion does each stage take place? What happens during each stage, what are the reactants and what are the products?arrow_forward
