In which of the following ways is photophosphorylation similar to oxidative phosphorylation in aerobic respiration? O FADH2 is involved in both pathways. Both use chemiosmosis. O NADH carries electrons to the electron transport chain in both pathways. Both use oxygen as a terminal electron acceptor.

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. Describe how ATP synthase uses proton motive force to make ATP Describe how NADH transfers electrons to electron transport proteins of the ETS and ultimately to the terminal electron acceptor, such as O₂. Explain how bacteria and archaea fix nitrogen gas into ammonium ion and incorporate nitrogen into biomolecules.

High-energy electrons from molecules of NADH and FADH2 are transferred to a chain of proteins within the electron transport chain. What is the final electron acceptor in the electron transport chain?

The energy of electron transport (by the ETC) serves to move protons (hydrogen ions, or H") to the intermembrane space of the mitochondrion. How does this help the mitochondrion produce ATP? O This movement of protons sets up the electrochemical gradient that drives ATP synthesis in the mitochondrion. O The protons receive electrons from the NAD+ and FAD that were accepted in glycolysis ad the citric acid cycle O The protons are transferred to oxygen in an energy-releasing reaction O The protons pick up electrons from the electron transport chain on their way through the inner mitochondrial membrane
