Why make Wikipedia useless?
Can someone create a simple version for people who want to understand mitochondria but aren't already extremely knowledgeable on the topic?
- Perhaps you would find the Simple English version more understandable. (There is a link to it in the lefthand column of the article page.) -R. S. Shaw (talk) 04:30, 7 August 2011 (UTC)
Should the Book/Movie/Game Parasite Eve be mentioned anywhere here? I mean, I dont know the original japanese story, but the video game version basically has mitochondria as rapidly evolving antagonists who were waiting for technological defenselessness (in the form of immune suppressing drugs) to "take over." The most prominent example of which is causing people to catch on fire through massive, commanded heat release.
The story is silly and clearly not scientifically accurate, but never the less, it is a cultural reference to mitochondria. Considering the sillyness however, I figured it was a good idea to get community input before posting much more about it. The big reason I see to include it is because it is basically the only well known example of science fiction directly using mitochondria as an antagonist. Which is weird but unique. Parasite Eve 2 goes so far overboard and is about a much different set of things, so neednt be included (it wouldnt help anyone understand anything that wasnt in the game.)126.96.36.199 (talk) 07:16, 11 October 2011 (UTC)
- I see that the Wikipedia page discussing midi-chlorians is linked to the mitochondrion page as is A Wind in the Door. --IONTRANSP (talk) 16:48, 11 October 2011 (UTC)
The Mitochondrion article needs a picture of a network of mitochondria
Have a look at ,say, an RK-13 cell at www.microscopyu.com brought to you by Nikon. See the network of mitochondria? Totally different picture from what we've got here in Wikipedia, with that stupid graphic of an isolated fooball-shaped or pill-shaped thing that you see after fixing and staining for the electron microscope. We've had these in vivo pictures of mitochondria available for at least twenty years now!Richard8081 (talk) 17:33, 5 January 2012 (UTC)
Is this paragraph correct?
"The decreased intra-mitochondrial calcium concentration increases dehydrogenase activation and ATP synthesis. So in addition to lower ATP synthesis due to fatty acid oxidation, ATP synthesis is impaired by poor calcium signaling as well, causing cardiac problems for diabetics."
First, it is said that the ATP synthesis is increased, but then it is said that it is impaired. Will increased dehydrogenase activity increase or decrease ATP synthesis? - Bob Collowân (talk) 18:05, 13 September 2012 (UTC)
- I think it should say "decreases dehydrogenase activation".
- The cited article says: "Importantly, mitochondrial Ca2+ concentrations in diabetic hearts were in the range where modulation of dehydrogenase activation occurs, suggesting that decreased flux through Ca2+-sensitive dehydrogenases may indeed contribute to impaired ATP generation in these hearts."
- I'm not sure that the mitochondrion page should discuss results from the article "Mitochondria in the diabetic heart". The article "Mitochondria in the diabetic heart" is not even cited at Mitochondrial disease. It might be best to simply link from this page to diabetic cardiomyopathy and make a page section there about the role of mitochondria. --IONTRANSP (talk) 18:59, 13 September 2012 (UTC)
Mitochondria in "most" eukaryotes
- Diplomonads as a group lack mitochondria (http://www.ncbi.nlm.nih.gov/pubmed/14614504). Microsporidia also lack mitochondria (http://www.ncbi.nlm.nih.gov/pubmed/9615449) and these have recently been shown to be fungi. There are few other amitochondrial protists. However, in all cases I am aware of, it has been shown that these are secondary loses of mitochondria, and not a primitive lack.Michaplot (talk) 20:58, 1 December 2012 (UTC)
All eukaryotes, even diplomonads etc., have mitochondria, at least as long as you define mitochondria as double membrane bounded organelles of bacterial descent. Only some "mitochondria" have completely lost their DNA (http://www.ncbi.nlm.nih.gov/pubmed/20124346). — Preceding unsigned comment added by 2001:620:400:9:0:0:0:55 (talk) 14:08, 15 March 2013 (UTC)
Merger proposal: Mitochondrial fission and Mitochondrial fusion
I propose that Mitochondrial fission and Mitochondrial fusion be merged into Mitochondria, maybe into a new section titled Fission and fusion. The fusion article is just a three-sentence stub, and the fission article is not much bigger and relies on primary sources exclusively. So there would be only little content to integrate into the main article. I am not sure on where to best place the information, though. As a subsection to Structure, or rather under Replication and Inheritance?--Biologos (talk) 15:15, 3 May 2013 (UTC)
- Great ! How about adding a sub-section in Replication and Inheritance as fusion and fission both contribute to the respective section ? Ghorpaapi (talk) 08:48, 4 May 2013 (UTC)
Pronunciation of mitochondria
Evidently a user and an IP disagree with me on how to pronounce the word "mitochondrion". I think it's pronounced /ˌmaɪtoʊˈkɒndʒɹi.ɪn/ (with a "j" sound where "dri" is, apparently they think its pronounced /ˌmaɪtoʊˈkɒndɹi.ɪn/ with just a 'da' and 're' sound (/dɹ/). Second thoughts on this issue would be appreciated.—Love, Kelvinsong talk 20:50, 24 August 2013 (UTC)
Error in Mitochondrion mini.svg
- Thank you for pointing this out. I removed the figure for the time being. I am not sure whether it should be re-added after correction, since we have enough other diagrams of mitochondria in the article.--Biologos (talk) 09:09, 14 March 2014 (UTC)
- Sorry, "cristal" seems to be used as the adjective for "cristae", it is quite widespread in the literature. I will undo my change.--Biologos (talk) 09:09, 14 March 2014 (UTC)
Why is this so very dry?
I wonder if this page might do a little more to explain the pivotal role Mitochondria played in the evolution of life? Perhaps a short paragraph including a link to Mitochondrial Eve might do it. I think this might satisfy our friend who made this comment https://en.wikipedia.org/wiki/Talk:Mitochondrion#Why_make_Wikipedia_useless.3F
No mention of mitochondrial decay
Mitochondrial decay redirects to this article, which however does not define or even mention the term. Could someone familiar with the concept please either say a word or two about it here, or change the redirect to an article in its own right? Vaughan Pratt (talk) 16:08, 31 October 2014 (UTC)
Please explain cryptic statement
In the 2nd paragraph under History, it's stated that "one oxygen atom can form two adenosine triphosphate molecules". Please explain how one oxygen atom can form anything other than one oxygen atom. Login54321 (talk) 10:42, 5 February 2015 (UTC)
- When you look at the adenosine triphosphate molecule, there are several atoms of oxygen within it. When you see it written that "one oxygen atom can form two adenosine triphosphate molecules", it just means that the bond between two molecules can be formed by one atom common to both, in this case oxygen. Hope this helps! – Paine EllsworthCLIMAX! 15:50, 5 February 2015 (UTC)
