Describe the role of each of the membrane proteins shown in the picture below. Think about what is happening to the electrons and describe how energy is transformed as electrons move along the chain. Part of this involves the formation of the proton gradient. The other part is the explanation of the energetics of electron transport that you investigated above. In other words, the reason that electrons always flow from complex I to complex III to complex IV to oxygen.
ATP synthase attaches a phosphate group to ADP, forming ATP .This process requires energy. The energy is provided by electron carrier molecules in the electron transport system that pump ___________into the intermembrane space (also called outer compartment).
