The cytochrome bd branch operates at low oxygen conditions. It is located in the outer membrane.
Explanation:
Electron transport chains of Escherichia coli are composed of different dehydrogenase and terminal reductase which is linked by quinones. It adjusts to different oxygen level because Oxygen is preferred electron acceptor and represses the terminal reductase of anaerobic.
