Talk:Photosynthetic reaction centre

message: Old wording was (bolding is mine): When an electron rises to a higher energy level, there is a corresponding increase in the reduction potential of the molecule in which the electron resides occurs.
Changed  increase to  decrease. The reduction potentials  decrease  (become more negative in value) instead of increase. For example, upon excitation the midpoint potential of P680 decreases from +1.1 V to -0.7 V..Plant Cell. 2005 Mar; 17(3): 648–663

==Bacteria and plants==
Reaction centres are present in all green plants and in many bacteria and algae. Green plants have two reaction centres known as photosystem I and photosystem II. A well understood bacterial reaction centre is that from the Rhodopseudomonus bacteria. Its photosynthetic reaction centre is much simpler than that of green plants and only consists of one protein complex.
Photosystem I typically includes 13 polypeptide chains, more than 60 chlorophyll molecules, a quinone and three 4Fe-4S iron-sulphur clusters. The total molecular mass is in excess of 800kd. Photosystem II contains at least 10 polypeptide chains, more than 30 chlorophyll molecules, a non-heme iron ion and four manganese ions.
Sequence analysis and structural comparisons between bacterial reaction centres and those from green plants reveal a reaction core which is remarkably similar, despite the increased complexity of the reaction centres found in green plants.
*I removed this because it is rather redundant with the rest of the article, and doesn't compare the bacteria and plants, as the chief purpose of the section was to do, probably. AndyZ 01:02, 1 March 2006 (UTC)

message: Small thing, in the article it says that "The electron chain that follows creates a highly reduced species such as quinone or NADPH, which is used in the Calvin cycle (the dark reactions) and in the Krebs cycle (the citric acid cycle)." I think that NAD+ is used in the Krebs cycle, not NADPH. AndyZ 01:13, 2 March 2006 (UTC)
replies: text: Correct. NAD+ is usedin the TCA cycle. David D. (Talk) 22:31, 4 March 2006 (UTC)

message: From what I have seen in text books the most common nomenclature used is chlorphyll a, not chlorophyll α. We should figure out a consensus for the standard nomenclature. Originally I had been using chorophyll a in wikipedia but I now notice that someone has gone through and reverted those edits to chorophyll α. A quick google gives over 6 million hits for chorophyll a, as opposed to 150,000 for chlorophyll α. I would side with using  chorophyll a as standard nomenclature throughout the photosynthesis articles in wikipedia. David D. (Talk) 22:39, 6 March 2006 (UTC)

message: I started this article some time ago before submitting it for a peer review and a request that it become a featured article. Although it never reached featured article status, maybe owing to its length and obscurity of subject matter, with the help of the users AndyZ,  Smurrayinchester, Durova, amongst others, it was brought up to good article status. I also earned my first (and thus far only) barnstar for my contributions to this article so I’m mildly confident that maybe it might be suitable for the test release of the fixed version of Wikipedia.Miller 20:59, 1 August 2006 (UTC)

message: The article is entitled centre, but the lede says center, and most of the article uses center (46 of 48 appearances!).  Should the article be retitled?  Or should the lede be improved?  Should all uses in the article be made consistent?  Or should the text explicitly suggest that both spellings are equally valid?  Yes, it's a nit, but it's the title of the article!
