Reaction centre edit

I started this article 22 days ago. I have put a lot of effort into it, hoping to create a high quality and scientifically accurate article. I don't think I'll manage to get this article featured due to its highly scientific nature, but I would still like experienced Wikipedia users to go over the article applying the 'picky-wiki' finishing touches to make sure it's of the highest caliber.Miller 20:35, 28 February 2006 (UTC) [reply]

Being scientific has no correlation with being featured- any article can be featured, and certainly main science articles have been finished. This article needs much work though. First off, the hierarchal structure of the TOC seems rather weak. I tried to fix it by incorporating both plant and bacterial reaction centers within the section. I would also prefer more wikification- there are very few links. The wording/prose is rather weak occasionally, making references directly to the reader. A question- it says that Photosystem II has subunits that are homologous to that of bacteria, but wouldn't they be analogous instead (not too sure)? Analogous indicates two things that serve the same function but had different origins. Since endosymbiosis caused chloroplasts to enter cells, I believe that it should be analogous. Another issue is that of inline citations. AndyZ 23:39, 28 February 2006 (UTC)[reply]
- Analogous means being two different things which are similar to one another (an analogy uses a simple principle to demonstrate a similar but complex principle). Homologous means been similar, but being the same thing, i.e. they share a common ancestor, as opposed to being two proteins which have followed different evolutionary paths which are similar, but perform different tasks. Such things do exist in biochemistry and they are referred to as analogous proteins. I'm not familiar with the fine details of wikification, I'm relying on experienced uses to do that.

- I believe the following layout would be more appropriate:

1)conversion of light
2)oxygenic photosynthesis
3)Bacteria and plants
3.1)bacterial reaction centre
3.2)photosystem II
3.3)photosystem I
4)references

Correct me again if I'm wrong- but I though that bacteria weren't related to plants unless you go really far back. Cyanobacteria are eubacteria, and I thought that it was believed that archaebacteria led to protists led to eukaryotes. So what about "The structure of Photosystem II is remarkably similar to the bacterial reaction centre and it is theorized that they share a common ancestor."? AndyZ 00:53, 1 March 2006 (UTC)[reply]
- Another note, algae was only mentioned one time in the entire article, and that mention I removed with the rest of the section I took out. I'm assuming that algae fall under the "oxygenic photosynthesis" section? I edited the layout to be more hierarchal. AndyZ 01:05, 1 March 2006 (UTC)[reply]

I think a better title for the article would be "photosynthetic reaction centre" as highlighted in the first sentence. There are presumably reaction centers of other kinds in other fields of chemistry and biochemistry that might be confused. SteveBaker 01:26, 1 March 2006 (UTC)[reply]
