Electron transport chains in the cells of various prokaryotic species can function in the presence of: a) O2 b) CO32- c) SO42- d) NO3- e) All of the above.
Electron transport chains in the cells of various prokaryotic species can function in the presence of:
a) O2
b) CO32-
c) SO42-
d) NO3-
e) Electron transport chains of bacteria (prokaryotes) operate in the plasma membrane. The electron transport chain is the last component of aerobic respiration and glucose metabolism.
In anaerobic respiration, inorganic compounds are used as electron acceptors such as SO42- and NO3-, CO32-. Hence electron transport chains in the cells of various prokaryotic species can function in the presence of all of the above.
The correct option is e.
a) In prokaryotic aerobic respiration, the final electron acceptor at the end of the electron transport chain is O2 molecule that becomes reduced to water.
b) CO32- carbonate ions in reduction of carbon dioxide.
