Talk:Metabolic pathway

message: Is it really necessary to have such a large space between the image and the next section "Cellular respiration". According to whoever added those spaces it was done for a 17" screen. I have a wide-screen computer, does this huge space still exist for anyone else?
Also, what exactly the point of the "Cellular respiration" section, if it is even that. As of now it's just a bolded title. Does the title and text following it refer to 'Metabolic Pathways and Cellular Respiration'? It's tite should be more specific. I'm also not sure that all of the text following the title actually belongs there, considering the fact that Photosynthesis and Chemosynthesis are certainly not processes of Cellular respiration. Does that make them part of a whole new section? Could someone who knows about this topic help figure this out as I am certainly no expert. --France3470 06:16, 7 May 2007 (UTC)

thread_title:  Some Questions 

message: If "all reactions are chemically reversible," why do charts of metabolic pathways often display arrows that aren't double-ended?  I think "all" should be changed to "most." Unfree (talk) 01:12, 30 November 2008 (UTC)
thread_title: Reversibility

message: I noticed the phrase "flux generating step" near the start of the article, what exactly is a flux generating step? I think such terms should be defined, unfortunately I've no idea what it is so I can't help. --Rhodydog (talk) 19:39, 6 January 2009 (UTC)
thread_title: Flux Generating Step

message: Should there be definitions to distiguish the words pathway, superpathway and map? The word superpathway which features heavily in metacyc and all those who cite it is quite handwaving, hence the question. --Squidonius (talk) 02:21, 29 May 2011 (UTC)
thread_title:  definitions 

message: See my comment in the talk of metabolic network. The two articles are basically overlapping and both slightly wrong. This article does not restrict itself to metabolism, and does not talk only of pathways, a notion that is now attached to directionality. Nowadays, one would talk about metabolic networks and signaling pathways. Sometimes of biochemical pathways/networks. But metabolic pathways is a notion that is fading rapidly because imprecise and slightly wrong (because of directionality).  Nicolas Le Novere (talk) 13:16, 16 November 2011 (UTC)

message: Top of page: "To initiate another metabolic pathway, called a flux generating step" - There is not such thing as a flux generating step, see Kacser and Burns, 1973 on Control of Flux. Rhodydog (talk) 18:46, 14 May 2014 (UTC)

thread_title:  External links modified 

message: I propose the following strategy for organizing this page and incorporating new material: I will add new sections and categorize them based on the classes and subclasses of metabolic pathways. It is important to expand on the topic by promulgating on the different types of pathways that occur in eukaryotes and prokaryotes. Furthermore, I will specify and briefly describe several important metabolic pathways and the roles they each play in the cell.
In addition, the provided information about metabolic pathways in this article lacks proper structure in order to be efficient in conveying that information; hence, I will rearrange some of the already mentioned material to allow for comfortable reading and a better conceptual understanding.
Finally, I intend to add proper citations for the information provided to allow for a smoother verification of the stated facts.
Any feedback on my proposition is greatly appreciated.

thread_title:  New map of Metabolic Pathways 

message: There are a lot of claims in the Overview section that are most likely true, but are not properly cited. For instance, the article claims that "Glycolysis was the first metabolic pathway discovered," but it does not provide a source. Avevanduz (talk) 22:30, 19 March 2017 (UTC)
thread_title: More Citations Needed

message: The last paragraph of the first section of this article(Metabolic pathway) is missing a word and does not make sense as it stands: "The end product of a pathway may be used immediately, initiate another metabolic pathway or be stored for later use." In addition to this minor grammatical issue, as noted by other users, this article is missing proper citation in some areas. Over all this article could be expanded to discuss more aspects of the full chart for metabolic pathways. Wasso392 (talk) 13:06, 21 March 2017 (UTC)

message: 1. "In most cases a metabolic pathway, the product of one enzyme acts as the substrate for the next."
Should it not be  "In most cases of a metabolic pathway"
2.  "However, set products are considered waste and removed from the cell."
     What are set products ? Should it not be "some products"  — Preceding unsigned comment added by Ruskin (talk • contribs) 08:57, 10 March 2018 (UTC)
thread_title:  1 st Para. Do these sentences make sense ? 

message: At present, it says: "In biochemistry, a metabolic pathway is a linked series of chemical reactions occurring within a cell.", but it's more than that. A pathway is a linked series of reactions that can sustain a steady state.  See "A general definition of metabolic pathways useful for systematic organization and analysis of complex metabolic networks", Schuster and Fell and Dandekar, Nature Biotech, 2000, 18, 326-332. These authors define pathways in terms of elementary modes which is a nice formal way of defining what exactly a metabolic pathway is. Rhodydog (talk) 22:15, 16 April 2018 (UTC)
