The citric acid cycle is a unique metabolic pathway because it is cyclic. Which statement BEST describes how it is cyclic? It is cyclic because oxaloacetate is regenerated. It is cyclic because CO2 is regenerated. It is cyclic because it is linked with oxidative phosphorylation. O All of the above are reasons that the citric acid cycle is cyclic.

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. Electron carriers are organized into four complexes of proteins and prosthetic groups. Prosthetic groups, such as iron-sulfur centers, are directly involved with electron transfer. Electron transfer in the ETC is coupled to proton transfer from the matrix to the intermembrane space. The reactions of the ETC take place in the outer membrane of mitochondria. Electrons generated by the citric acid cycle in the mitochondrial matrix enter the ETC. The outer membrane of mitochondria is readily permeable to small molecules and hydrogen ions. Electron carriers in the mitochondrial matrix include ubiquinone (coenzyme Q), FMN, and cytochrome c.
