Aerobic
Carbon monoxide is a gas that can block aerobic metabolism by binding to hemoglobin in red blood cells more strongly than oxygen, preventing adequate oxygen delivery to tissues. This interference can disrupt the cell's ability to use oxygen for energy production through aerobic metabolism.
Initially, no. Anaerobic exercise is really a misnomer. The work done still requires oxygen it is just that the oxygen is supplied eventually and not while performing the action. This is because the body is using glucose to the point of producing lactic acid. This is feasible for a short period of time, but eventually the oxygen debt created while using this pathway has to be repaid to deal with the lactic acid by converting it back into glucose. A good example is a sprint. After the end of the sprint there is a period of recuperation and panting required.
Anaerobic metabolism converts glucose into energy without the use of oxygen. This process results in the production of lactate or lactic acid as a byproduct.
Facultative anaerobic bacteria can switch between using aerobic and anaerobic metabolism depending on oxygen availability. Obligate anaerobic bacteria cannot survive in the presence of oxygen and rely only on anaerobic metabolism, while obligate aerobic bacteria require oxygen for survival and use aerobic metabolism exclusively.
METABOLISM. Metabolism is the sum of the group of reactions to obtain energy and basic compounds from food (catabolism), and the group of reactions to form organic molecules and to use energy obtained form food (anabolism).
Aerobic metabolism requires the use of oxygen. In this process, glucose is broken down in the presence of oxygen to produce ATP, the cell's energy currency. Aerobic metabolism is more efficient than anaerobic metabolism, which occurs in the absence of oxygen.
Aerobic microorganisms require oxygen to survive. These organisms use oxygen in their metabolism to generate energy for growth and reproduction.
A facultative anaerobe can switch between using oxygen and not using oxygen for metabolism, while a facultative aerobe can only use oxygen for metabolism.
Anaerobic organisms do not use oxygen in their metabolism. These organisms can generate energy through fermentation or anaerobic respiration, which does not require oxygen. Examples include certain types of bacteria and yeast.

Aerobic organisms, such as mammals, birds, and many types of bacteria, can use gaseous oxygen in their metabolism. This process is known as aerobic respiration, where oxygen is used to produce energy through the breakdown of organic molecules.

Oxidative metabolism, in the words of my Biology professor, is the use of oxygen, release of carbon dioxide, and most ATP formation in the metabolic pathway.
Organisms which need oxygen are called aerobic organisms or aerobes. The oxygen is used in the process of respiration to release energy from food. Organisms which do not use oxygen in respiration are called anaerobic organisms or anaerobes. See: http://en.wikipedia.org/wiki/Aerobic_organism
