Compare aerobic and anaerobic respiration. Please give a tally of how many ATP molecules are made in each type of metabolism. If one type of metabolism yields more ATP, explain why.

Aerobic respiration is a process that requires oxygen, but in anaerobic respiration, oxygen is not required. Aerobic and anaerobic respiration differs in terms of the amount of energy that is produced. A lot of energy is produced during aerobic respiration; this could be as high as 38 ATP molecules for every glucose molecule. This means that during aerobic respiration only one molecule of glucose will produce about thirty-eight energy units. Anaerobic means where there is no air and thus anaerobic respiration is a term used for the respiration that occurs without the use of oxygen. In this process, the molecules carry oxidation, when oxygen is absent. This results in the production if energy or ATP. This type of respiration is also equivalent to fermentation when energy production path (Glycolytic pathway) is functioning in one cell. There are two processes of this respiration (i) alcoholic fermentation, where the Glucose gets broken down and produces Energy (ATP), Ethanol and Carbon Dioxide as well as (ii) Lactate fermentation where Glucose breaks itself into Energy and Lactic Acid. Anaerobic respiration produces less energy in comparison to aerobic respiration. When the anaerobic respiration (alcoholic fermentation) as at one above functions, only two molecules of ATP are given out for one glucose molecule, while for lactate fermentation as at two above, 2 ATP molecules are given out for each glucose molecule used during the process. Thus, during anaerobic respiration, only one molecule of glucose is broken down to obtain only 2 ATP molecule.
