Q1. Describe how NADH transfers electrons to electron transport proteins of the ETS and ultimately to the terminal electron acceptor, such as O2.
Q2. Explain how the transfer of electrons from one electron transport chain complex to the next, yielding energy, is coupled to the pumping of H* across the membrane.
Q3. Describe how ATP synthase uses proton motive force to make ATP
Q4. Explain how bacteria and archaea fix nitrogen gas into ammonium ion and incorporate nitrogen into biomolecules.
