Question
There are many types of microbial metabolism, beyond those covered previously. The terminology below describes metabolic types. Match each metabolic type with the best description. Match the terms letters with the numbers
a)Ferrous iron oxidation
b)Nitrification
c)Aerobic ammonia oxidation
d)Acetogenesis
e)Anaerobic oxidation of methane (AOM)
1)is performed by obligate anaerobes that use H2 as the major electron donor; both ion pumps and substrate level phosphorylation are used to conserve energy.
2)is performed by Archaea and Bacteria and produces nitrite; Bacteria may oxidize the nitrite to nitrate.
3)is performed by Archaea, often in sewage and in freshwater sediments; CO2 is often reduced using H2.
4)involves the aerobic oxidation of ammonia or nitrite.
5)can be aerobic or anaerobic; only small amounts of energy can be produced in acidic environments even though many of the organisms using this are acidophilic.
