Key Points d) Mitochondrial matrixWhich of the following are electron donors during ETC? a) NADH and FADHb) NADPH and FADHc) ATP, NADH and FADHd) NADH and FMN An electron transport chain, or ETC, is composed of a group of protein complexes in and around a membrane that help energetically couple a series of exergonic/spontaneous red/ox reactions to the endergonic pumping of protons across the membrane to generate an electrochemical gradient The Electron Transport System (ETS) or Electron transport chain is present in the inner mitochondrial membrane. c) Inner Mitochondrial membrane. b) Outer Mitochondrial membrane. The electron transport system is the process in the cell where electrons, generated by oxidation are transferred. It contains several electron transporters in a series, which facilitate the movement of electrons from one carrier to another in redox reactions The electron transport chain uses the electrons from electron carriers to create a chemical gradient that can be used to power oxidative phosphorylation. Learning Objectives. The passage of the electrons through the system generates Where do NADH and FADH2 come from (circle all that apply)? a) Mitochondrion. Several electron transporters are Take this Electron Transport Chain (ETC) practice exam questions with answers quiz and evaluate for yourself. Glycolysis Fermentation Krebs CycleWhere does the ETC occur?While on the ETC, electrons are The electron transport chain uses the electrons from electron carriers to create a chemical gradient that can be used to power oxidative phosphorylation. Describe how electrons move through the electron transport chain. How do the mitochondria maintain the chemiosmotic gradient used for the electron transport Located within the inner mitochondrial membrane, the ETS (Electron Transport System) or electron transport chain performs its functions. An ETC is a series of four protein complexes (and/or other molecules) that couple redox reactions and transfer electrons from electron donors to electron acceptors Which is the site of Electron Transport Chain?
