How soon depends on the quality of embalming, burial container, burial location (such as mausoleum or in-ground). One funeral director I know exhumed a body 5 years after it was buried.
Definition: Aerobic metabolism is the creation of energy through the combustion of carbohydrates and fats in the presence of oxygen. The only byproducts are carbon dioxide and water, which your body disposes of by breathing and sweating.
Aerobic respiration is the process in which a compound is oxidized using oxygen as the terminal electron acceptor. That definition probably doesn't make much sense yet, but by the end of the lesson it will come together.umans consume food for energy and use oxygen for respiration in a process referred to as metabolism. Believe it or not, bacterial cells carry out almost exactly the same processes. Understanding bacterial metabolism can be difficult.
