Is H1N1 an obligate aerobe or anaerobe?
Neither. H1N1 is a virus, which means it doesn’t have its own metabolic machinery. Essentially, a virus is just a little packet of genetic material (DNA, RNA, or both) and the few proteins it needs to invade a living cell. Once it has invaded a cell, it will use the cell’s native metabolic machinery to generate ATP to fuel chemical reactions.
