Question Completion Status: The respiratory chain is a set of four complexes whose role is to transport electrons from reduced co factors to dioxygen. The entry from previous blank) are shuttled from complex NADH oxidoreductase to complex Q-cytochrome coxidorreduc to complex cytosome c-oxidase The transfer of electrons is associated with a release of which allows to pass from the mitochondrial matrix into the intermembrane space. Given that the internal membrane is impermeable, an electro-chemical gradient of protons will thus form...

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...

Overall electron flow in a cell using reverse electron transport Consider a cell that is using reverse electron transport to generate NADH and is not (for the moment) using the proton gradient for anything else. Assume the cell is not a phototroph (so electrons are not being recycled by light-driven pumping). Also assume that the proton gradient is produced solely by a Q-cycle like the one we've discussed, which pumps 2 protons per electron transferred. (This would imply that the...

9. In the electron transport chain picture above, how do electrons move from protein complex I to protein complex II? 1. I need you to remember that "Q" is ubiquinone which gets reduced at proteins l & I, and oxidized at protein III. "Reduced" means gains electrons, "oxidized" means loses electrons. 2. I need you to remember how "Q" moves from protein I to protein Do you remember? Don't overthink it, Preeda. As far as scientists know right now, the...
