Did archaea breathe oxygen? Explained by Sharing Culture

Archaea exhibit a great variety of chemical reactions in their metabolism and use many sources of energy. These reactions are classified into nutritional groups, depending on energy and carbon sources. Some archaea obtain energy from inorganic compounds such as sulfur or ammonia (they are chemotrophs). These include nitrifiers, methanogens and anaerobic methane oxidisers. In these reacti… WebThe engulfed (endosymbiosed) bacterial cell remained within the archaean cell in what may have been a mutualistic relationship: the engulfed bacterium allowed the host archean cell to use oxygen to release energy stored in nutrients, and the host cell protected the bacterial cell from predators.
