The correct answer is A that proton motive force because The electron transport chain forms a proton gradient across the inner of proteins and organic molecules found in the inner membrane of the mitochondrial gradient, which is then used to make ATP in a process called chemiosmosis.The gradient is sometimes called the proton-motive force

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...
The electron transport chain consists of protein complexes embedded in the inner mitochondrial membrane, where it generat a proton gradient by a series of oxidation-reduction, or redox, reactions. Although all of the stages of cellular respiration (glycolysis, the citric acid cycle, and the electron transport chain) are necessary for life, the electron transport chain is sometimes called the most important stage. First complete the sentence, then answer the question. The electron transport chain uses the transfer of protons between protein...

View Avallable Hint(s) 0 to provide the driving force for the synthesis of ATP from ADP and P, O to tunction as the final electron acceptor in the electron transport chain O to oxidize NADH and FADH2 from glycolysis, acelyl CoA formation, and the citric acid cycle O to provide the driving force for the production of a proton gradient
The electron transport chain (ETC), or respiratory chain, is linked to proton movement and ATP synthesis. Select the statements that accurately describe the electron transport chain. Choose all that apply.Prosthetic groups, such as iron-sulfur centers, are directly involved with electron transfer. The reactions of the ETC take place in the outer membrane of mitochondria. Electron carriers in the mitochondrial matrix include ubiquinone (coenzyme Q), FMN, and cytochrome c. The outer membrane of mitochondria is readily permeable to small molecules and hydrogen ions. Electrons generated...
