@EditSafe: May you revert the title back to "Carbon reactions" please? This needs an RM. --George Ho (talk) 11:07, 8 March 2017 (UTC)
@George Ho: Why? — Preceding unsigned comment added by EditSafe (talk • contribs) 22:24, 8 March 2017 (UTC)
Carbon reactions could refer to several different things, in fact if you search carbon reactions into google search engine, you will find pages like this as the top results https://www.webelements.com/carbon/chemistry.html http://www.elementalmatter.info/carbon-reaction.htm http://www.chemistryexplained.com/elements/A-C/Carbon.html https://www.reference.com/science/carbon-react-9af044c956cbe8da which have nothing to do with photosynthesis, in fact I can find very little that even says that this term for the reactions is commonly known as carbon reactions. I think it would be best to move it back to "light-independent reactions" or "carbon fixation" or some other name that is more common, but if we are keeping it at this name we should atleast include that it is referring to the cycle, not to general reactions involving carbon.

Requested move 9 March 2017
After the move
Whatever happens to the move, there's some refactoring required to the article. As a start we should make sure each of the redirects that points here either points to an appropriate section or is mentioned and bolded in the article lead. If to a section, then it should either be the section heading (or close, dark reaction and dark reactions can just point to the same heading for example) or the redir should be mentioned and bolded early in the section. We're a general encyclopedia, remember, and try to respect the principle of least astonishment. Andrewa (talk) 05:08, 28 March 2017 (UTC)
- I just saw the note from George Ho at WT:MCB. Sorry I don't have time to work on this article myself now, but from a quick look I can offer a few suggestions:
- The outcome of the page move was a tad unfortunate, as "Calvin cycle" would have been a much better name. It's the more common term both in the academic literature and on the web in general, plus it has the advantage in a general encyclopedia of not being misleading – these reactions are not light independent at all as they rely on energy and reducing power from the light dependent reactions, and cannot occur in the dark.
- The end product of the Calvin cycle is, uncontroversially, glyceraldehyde-3-phosphate. The article currently names glucose as an end product, which is incorrect (for the Calvin cycle at least; I'm not sure what is meant by "carbon reactions"). I think what happens to the G3P varies by plant, but that's not part of the Calvin cycle.
- The lead should not be as "plant-centric" as it currently is, as the Calvin cycle is not specific to plants, but occurs in all photosynthetic organisms, including algae, cyanobacteria, and some protists.
- The focus of this article ought to be essentially what's depicted in File:Calvin-cycle4.svg. A bit of info about chloroplast structure, the light reactions, the fate of G3P, and CAM photosynthesis is appropriate for background and context, but it should be clear where the Calvin cycle itself begins and ends. Carbon fixation is a distinct concept; it should be mentioned as part of the Calvin cycle, but it should also be clear that it can occur by other means. Adrian J.
