Monera Oxygen Requirements Respiration of eubacteria may be aerobic or anaerobic. The anaerobes undergo a form of respiration called fermentation. Among anaerobes, some can live in the presence or absence of oxygen. These are called facultative anaerobes. Some are indifferent to the presence of oxygen, but others have two respiratory pathways, one that uses oxygen and one that does not. The other group of anaerobes, the obligate anaerobes, are actually poisoned in the presence of oxygen. Motility Many eubacteria are motile. In most cases, rotating structures called flagella enable them to move. The term flagella is also used to refer to similar motility structures in protists and other eukaryotic cells, but the two are not the same and should not be confused. Prokaryotic flagella are composed of protein subunits called flagellin, while eukaryotic flagella are made of arrays of microtubules made of tubulin. Prokaryotic flagella are anchored in the plasma membrane and move in a spiral motion. Eukaryotic flagella are
