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.

Oxidative phosphorylation is achieved through chemiosmotic coupling, which turns chemical energy into osmotic potential energy that is used to synthesize the energy “currency” of the cell (ATP). This process is divided into stage 1 (electron transport chain) and stage 2 (ATP synthase). Answer the following questions about each stage: In stage 1, what is the energy source used to form the proton gradient across the inner membrane and what is the principal carrier of this energy source? In stage 2, the total potential energy (proton-motive force) stored in the proton gradient used to power ATP synthase is composed of two components. What are these two components?
