The first sentence of the second paragraph for the definition of "Life" begins "Living organisms undergo metabolism,..." The first sentence here ends "...to sustain life" Now I know that it is very easy to find thousands of examples of this in all dictionaries; however, in the definition here for metabolism, the word "life" is the most crucial word. The definition for "Life" (in Wikipedia) is dependent on listing the processes that define it--metabolism being one. I will be giving an assignment to my class which will require taking the stand that rocks are living. An argument to the contrary would not be helped by these circular definitions. And no, I'm not sure how to fix it. — Preceding unsigned comment added by 208.180.62.14 ( talk) 20:23, 4 May 2012 (UTC)

This edit by 66.215.123.233 looks like a general theory of metabolism. However, it is not backed by sources. The description of biological systems as Dissipative systems is important.

I propose merging both cell metabolism and total metabolism with this page and replacing these articles with redirects. TimVickers 23:38, 5 March 2007 (UTC)
(also called metabolism) is all of a certain living organism's chemical processes. The organism's metabolism can be dichotomized into the synthesis of organic molecules ( anabolism) and their breakdown ( catabolism). This is to be distinguished from cell metabolism which is those processes of metabolism that occur within a single cell. The study of total metabolism is called metabolomics.
Some organisms can reduce their metabolism to almost zero for certain periods of time. Spores of fungi can survive thousands of years in that state. But every lifeform is bound to have metabolism at some point of its life cycle.
Human cells obtain most of their energy from chemical reactions involving oxygen. A starting point in measuring human metabolism is with basal metabolic rate. Some microbes metabolise the wrought iron on shipwrecks, forming structures known as rusticles with the waste compounds they produce.
Proposed major sections in new version TimVickers 19:25, 6 March 2007 (UTC)
"A striking feature of metabolism is the similarity of the basic metabolic pathways between even vastly different species. For example, the series of chemical steps in a pathway such as the citric acid cycle is universal among living cells as diverse as the unicellular bacteria Escherichia coli and huge multicellular organisms like elephants."
Maybe I'm nitpicking, but I'm not sure what is meant by "universal" here. Does it mean that the citric acid cycle is found in all organisms? Many bacteria appear to be missing several genes encoding the enzymes of the citric acid cycle. Several bacteria don't seem to encode any of these enzymes. NighthawkJ 03:09, 16 May 2007 (UTC)
The wikilinking of 'group transfer reactions' is incorrect. A wikilink must take you to an article expanding that term or containing its explanation. In this case it takes one to functional groups. If no wiki on group transfer reactions exists, it should be made. The functional groups wiki will naturally occur in the explanatory text of what the group transfer reactions are. Even a stub with a few lines is preferable to an inappropriate wikilink. Regards, AshLin 20:05, 21 July 2007 (UTC)

This article is linked to the Swedish article "Metabolism". However, while this article defines metabolism as the processes in the cell, the Swedish word means processes in organisms, including multicellular organisms. I therefore ask whether the english word might also include processes outside the cell, for example trypsin digestion of proteins in the stomach? In that case the definition in the introduction needs to be changed slightly. Etxrge ( talk) 19:34, 5 December 2007 (UTC)
The kernel meaning of catabolism is that molecules are divided into smaller molecules. See the article, and e.g. [1]. As a consequence energy is (often) extracted. Photosynthesis provides energy but cannot reasonably be seen as dividing molecules. It rearranges atoms. The major end result is glucose, which is much bigger than the input molecules. photosynthesis is not a catabolism. -- Etxrge ( talk) 13:44, 15 December 2007 (UTC)
I can see the logic of this article and I think it is a good way to present it. Clearly the light reaction have more in common with the catabolic electron transport in mitochondria than anything. On the other hand carbon fixation is clearly anabolic (essentially the reverse of glycolysis) . I prefer to think of photosynthesis as two processes, light reaction and light independent reaction, as it make the whole of photosynthesis more logical. On the other hand I can understand that the overall process of photosynthesis could be regarded as anabolic. i.e. the simplistic notion that photosynthesis is carbon dioxide + water + light energy → glucose + oxygen + water. The problem I have with the latter presentation is it is not really accurate to consider it as one process and can lead to misconceptions like the oxygen is released from the carbon dioxide rather than from water during carbon fixation. David D. (Talk) 23:06, 17 December 2007 (UTC)
I was astonished to discover that there is not a single reference anywhere in the article to the role of the Endocrine system in regulating the metabolism. I realize that not all organisms have an endocrine system -- but this is still a major oversight, imo. Surely there should be a section addressing this issue.

Greetings, Wikipedia users.
I am an AP Biology high school student with plans to synthesize and article that would have the caliber to attain the Good Article status. However, a perfect score on this assignment can be consumnated if the article achieves the Featured Article status. Thus, I have been contemplating about a topic would have the potential to meet these guidelines. I deduced that perhaps an "Introduction to Metabolism" article could fulfill the requirements. Would this be an advisable approach. After all, Introduction to Evolution, a featured article, my teacher's article, followed in the footsteps of the existing Evolution article. I am open to all suggestions and feedback.
This is a project that is not due until next year, so I have a reasonable duration of time to ponder over this notion. Here is the link to our class page that identifies our goals and project information: Wikipedia:WikiProject AP Biology 2008

This is a great description of metabolism, simple and clear. At one point "quickly and efficiently" is used. The word "efficiently", needs to be replaced with what it means to be efficient in metabolism, using the language and ideas of metabolism. — Preceding unsigned comment added by 76.28.130.42 ( talk) 14:03, 5 September 2011 (UTC)
I'm curious, why does it come at the end of the article? Kristephanie ( talk) 01:18, 6 September 2011 (UTC)
The structure shown for ATP is incorrect, as it shows the phosphate groups to be fully protonated.
Adenosine triphosphate is present, as the name says, as the phosphate and not the "phosphoric acid". The acidity constants, pKa, of the three primary phosphate protons are below 2; the final proton is situated at the terminal phosphate group of the triphosphate chain of ATP and has a pKa of about 6.5. In other words, at the physiological pH of about 7.6 ATP is overwhelmingly present as a tetravalent anion. In addition, it should be noted that all the other phosphate compounds depictured in this article are deprotonated as well at the physiological pH.

Sorry. I don't know where else to ask this question. Animals need so many pounds of food (Intake) to maintain so many pounds of weight. For example, dogs need more food per pound of weight than do cats. Dogs have "more energy" (use more energy). There must be statistics on this. And a name for them. Can anyone help? Thanks. Student7 ( talk) 19:06, 30 January 2012 (UTC)
The definition of "intermediary metabolism" in Oxford Dictionary of Biochemistry and Molecular Biology matches the definition here very well - the totality of the chemical reactions in the cells. The same book defines "metabolism" as either "the totality of chemical reactions and physical changes that occur in living organisms" or the chemical reactions that a specific molecule undergoes in a living organism (like drug metabolism). I expanded the beginning of the article slightly, and made sure intermediary metabolism and intermediate metabolism points here. The reason I don't state the dictionary as a source in the article is I have written slightly different - expanding, explaining, interpreting what's in the dictionary. So I can't really claim that everything in this edit is from that book. -- Siden ( talk) 09:16, 19 February 2012 (UTC)
Is it possible to get the navboxes to collapse so they dont take up nearly as much space as the article? • • • Peter (Southwood) (talk): 09:46, 11 April 2013 (UTC)
I've been keeping an eye on Metabolism lately, and I see the latest reverted edit may have some significant information. An IP, 24.154.111.112, added the following to the TOP of the article:
Benzene as it applies to Metabolism on a cellular level is not an organic solvent. It is however, on a microscopic scale, a quantum coupling agent. There is a very large difference between organic solvents and quantum coupling agents on a microscopic scale.
Now, while the position of this text at the top of the page was non-standard, the material itself might be worthy of attention. The only mention of Benzene in the article is the following:
[...] Lipids are usually defined as hydrophobic or amphipathic biological molecules that will dissolve in organic solvents such as benzene or chloroform. [...]
So, does it mislead readers who will infer that benzene is used by the body to dissolve lipids? I've read that Benzene is metabolized mostly in the liver and very quickly. Its byproducts are used by our cells to produce more energy. If, as the IP suggests, Benzene is not used to dissolve lipids, then this article should not tell readers that it does, isn't that so? I'm not an expert and will gladly defer to those who are. – Paine Ellsworth CLIMAX! 08:38, 2 October 2013 (UTC)
Hello, about this talk . I found the original source which was from OXFORD DICTIONARY OF Biochemistry and Molecular Biology which published at 2000 . The book has been revised at 2006 and defined the lipid can be dissolved with lipid solvent, not organic solvent. I want to edit the article but i am afraid to do that cause of these article was an FA. I found another mislead resource about steroid as major classes of lipid. I have been known that steroid is not that, but the sterol is the major class. They are different definition. Anyone can give me advice to edit that. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3995129/ this is my source User:Agus Damanik| User talk:Agus Damanik Agus Damanik ( talk) 14:16, 6 June 2020 (UTC)

Now, while the position of this text at the top of the page was non-standard, the material itself might be worthy of attention. The only mention of Benzene in the article is the following:
[...] Lipids are usually defined as hydrophobic or amphipathic biological molecules that will dissolve in organic solvents such as benzene or chloroform. [...]
So, does it mislead readers who will infer that benzene is used by the body to dissolve lipids? I've read that Benzene is metabolized mostly in the liver and very quickly. Its byproducts are used by our cells to produce more energy. If, as the IP suggests, Benzene is not used to dissolve lipids, then this article should not tell readers that it does, isn't that so? I'm not an expert and will gladly defer to those who are. – Paine Ellsworth CLIMAX! 08:38, 2 October 2013 (UTC)
Hello, about this talk . I found the original source which was from OXFORD DICTIONARY OF Biochemistry and Molecular Biology which published at 2000 . The book has been revised at 2006 and defined the lipid can be dissolved with lipid solvent, not organic solvent. I want to edit the article but i am afraid to do that cause of these article was an FA. I found another mislead resource about steroid as major classes of lipid. I have been known that steroid is not that, but the sterol is the major class. They are different definition. Anyone can give me advice to edit that. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3995129/ this is my source User:Agus Damanik| User talk:Agus Damanik Agus Damanik ( talk) 14:16, 6 June 2020 (UTC)

What does 'protagon acid cycle' imply in section Metabolism#Oxidative_phosphorylation? The term protagon was used to describe a mixture of various substances from brain extract as in this journal, but I cannot find any article relevant to oxidative phosphorylation. -- SongofSol ( talk) 04:07, 4 October 2014 (UTC)
