Mitochondria origin[edit]

Great article - clear, informative & useful - thanks! Just one minor point ( and apologies if Im wrong).

The final sentence in the current article - "This finding was the final confirmation that hydrogenosomes are indeed derived from mitochondria. [4]", citing, amongst others, Boxma et al, Nature 2005 434:74-79, makes a generalisation that seems to go beyond the current evidence.

Such a claim would be fine if limited to the hydrogenosome Nyctotherus ovalis, based on the Nature paper.

However, in the same issue of Nature, an article by Michael W. Gray Nature 434, 29-31 (3 March 2005) emphasises that the lineage of other hydrogenosomes such as Trichomonas vaginalis is much murkier. Consequently, he says, the story of the origin of hydrogenosomes is far from complete. In this Nature article, Gray concedes " it seems that nature can evolve a hydrogenosome from a mitochondrion with relative ease". However, at the same time, he points out that some studies of Trichomonas suggest it is not derived from mitochondria, but more remotely shares a common ancestor.

I'm no expert at all in this area, but it looks as though the article could be improved by insertion of the word "some" (or "at least one"). But I'll happily bow to anyone with real knowledge of the field. -- Reflection

Differences from mitochondria[edit]

Pyruvate is take by the hydrogenosome and H2, CO2, acetate, and ATP are produced.NOTE THAT IT LACKS CRISTAE THAT PRESENT IN MITOCHONDRIA + LACKS TCA IN PALSMA!! —Preceding unsigned comment added by (talkcontribs)

Some labels in the image are misspelled[edit]

Pyruvate in the image is spelled as "pyruvat". Same idiosyncrasy for succinate. In fact the name of file is "Hydrogenosom", again missing the e.Chibibrain (talk) 05:10, 21 November 2009 (UTC)


This article contains a lot of jargon without an explanation as to layman's terms and should probably be dumbed down for laypeople. —Preceding unsigned comment added by (talk) 16:45, 8 April 2010 (UTC)
