RESPIRATION IS NOT BREATHING - BREATHING IS INHALATION!!! Respiration is extracting chemical energy and converting it to something useful! —Preceding unsigned comment added by 88.111.48.85 (talk) 18:43, 21 November 2008 (UTC)

respiration can be confused with gasiouse exchange, but they have vastly different features.I've redirected Breathing here for now -- but this page is about oxygen & CO2, not about lungs and the diaphragm etc. I'll leave it to the biologists to decide whether to add that here or create an article at Breathing -- Tarquin 18:41 Dec 29, 2002 (UTC) Respiration is different from breathing. Respiration is the cemical binding of Glucose and oxygen to form energy, while breathing refers to the process in which air travels to and from the lungs.

When someone does get around to making a page on breathing they should add a link to bell jar model lung.-- Theresa knott 08:59 Feb 25, 2003 (UTC)

Moved from the vllage pulp: Are there any biologists out there who can look at the page respiration. It looks wrong to me. What this page describes is what I would call gas exchange. I would guess that most people querying a search engine on respiration would be looking for cellular respiration, not this. Theresa knott 13:29 9 Jun 2003 (UTC)

In french, respiration has clearly *two* senses in biology. I guess it is the same in english, except if breathing is the second term used, but I *really* doubt so. Afaik, the term has two meanings : the first is described here : that is the physiological respiration, the second term is the biochemistry one to which you refer in the pump. It makes perfect sense to me that the two explanations stay at the same place, but the two meaning should be introduced at the beginning of the article for clarity. I don't think it is confusing at all (as long as it is clearly initially defined) and I don't think one can say one definition is expected more than the other. Of course, I might be wrong :-) user:Anthere

Cellular respiration describes the metabolic reactions and processes that take place in a cell or across the cell membrane to get biochemical energy from fuel molecules and the release of the cells' waste products. Energy can be released by the oxidation of multiple fuel molecules and is stored as "high-energy" carriers. The reactions involved in respiration are catabolic reactions in metabolism.

Fuel molecules commonly used by cells in respiration include glucose, amino acids and fatty acids, and a common oxidizing agent (electron acceptor) is molecular oxygen (O2). There are organisms, however, that can respire using other organic molecules as electron acceptors instead of oxygen. Organisms that use oxygen as a final electron acceptor in respiration are described as aerobic, while those that do not are referred to as anaerobic.

The energy released in respiration is used to synthesize molecules that act as a chemical storage of this energy. One of the most widely used compounds in a cell is adenosine triphosphate (ATP) and its stored chemical energy can be used for many processes requiring energy, including biosynthesis, locomotion or transportation of molecules across cell membranes. Because of its ubiquitous nature, ATP is also known as the "universal energy currency", since the amount of it in a cell indicates how much energy is available for energy-consuming processes. —Preceding unsigned comment added by 172.201.239.93 (talk) 16:51, 27 March 2008 (UTC)

Ok I've gone ahead and changed the page to give the two meanings at the top of the page. Theresa knott 08:29 10 Jun 2003 (UTC)
