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...

Cytochrome c oxidase is the last enzyme in the respiratory electron transport chain of mitochondria. It receives an electron from each of four iron-containing cytochrome c molecules and transfers the electrons to one oxygen molecule, converting molecular oxygen to two molecules of water. In the last step of the process, water is produced. The unbalanced equation for the redox reaction is: Fe2+(aq)+O2(aq)=Fe3+(aq)+H2O(l) Write the balanced equation for the reaction under acidic conditions. Include charges and states where appropriate. Use the...

Electron transport chain. The enzyme succinate dehydrogenase is part of the citric acid cycle (Fig. 17.15) and the electron transport chain (Fig. 18.6). Calculate the free energy (ΔG) of the reaction catalyzed by succinate dehydrogenase under physiological conditions: 2 mM succinate, 0.5 mM fumarate, 2 mM FAD, and 0.2 mM FADH2. [Recall that ΔG = -n F ΔEo. See Table 18.1 for the relevant standard reduction potential (ΔEo).]
