Q:

What organ cells undergo aerobic respiration?

A:

Quick Answer

According to Georgia State University, aerobic respiration is characteristic of eukaryotic cells, and most of it takes place in the mitochondria. Aerobic respiration gives organisms the ability to convert food into chemical energy and provides cells in the human body with enough oxygen to function.

According to Kimball's Biology, cellular respiration is the process of oxidizing food molecules, such as glucose, to carbon dioxide and water. The energy released is trapped in the form of ATP for use by all the energy-consuming activities of the cell. The carbon dioxide binds with water to form carbonic acid, helping to maintain the blood's pH. Since excess carbon dioxide lowers the blood's pH, it is removed by the cells on an ongoing basis.

Aerobic respiration takes place within the mitochondria of the cell, which consists of an outer membrane, inner membrane and small number of DNA molecules. The outer membrane contains proteins that allow a variety of molecules and ions to move in and out of the mitochondria, whereas the inner membrane contains a number of membrane proteins that help the cells function properly. According to Science Clarified, some forms of respiration are anaerobic, meaning that they require no oxygen. Such is the case, for instance, with some bacteria, such as those that convert ethyl alcohol to vinegar.
