[edit] Merge

I'm going to merge many of the chemiosmotic stuff under this name. I think that it makes more sense to have one entry under chemiosmosis rather than seperate entries for Chemiosmotic hypothesis and Chemiosmotic phosphorylation. Rozzychan 23:12, 22 July 2006 (UTC)

[edit] Let the games begin

OK, I made the new article. I need references, images, and more depth on chemiosmosis in plants and bacteria. I also need someone to check the existing references. I copied them straight using two articles and do not know if they still are numbered correctly.

I hope to remove the entries for Chemiosmotic phosphorylation and Chemiosmotic hypothesis which I copied in entirety

[edit] Suggestion for the key points to make while introducing chemiosmosis (chemiosmotic coupling)

  1. describe the terminal phosphate bond of ATP as the key "energy currency" of cells
  2. state that chemiosmosis is widely used (mitochondria, chloroplasts, bacteria) in living cells as a way to channel chemical energy into ATP.
  3. chemiosmosis requires a topologically close cellular or subcellular compartment surrounded by a lipid bilayer membrane - this was a surprise to biochemists and its discovery resulted in a Nobel prize.
  4. lipid bilayer membranes are poorly permeable to protons
  5. chemical energy can be used to pump protons across membranes
  6. chemical energy can be stored in the form of a proton gradient across a cell membrane
  7. energy from a tranmembrane proton gradient can be captured to produce ATP

[edit] chemiosmosis coupling

Someone needs to add some info on chemiosmosis coupling —The preceding unsigned comment was added by LtGeneral Snow (talk • contribs) 22:01, 6 December 2006 (UTC).

[edit] Proposed merger

I think the material on the Proton-motive force page could make a good section in this article and the Chemiosmotic hypothesis article could be added as a "History" section as it deals mostly with Peter Mitchell. TimVickers 18:18, 16 March 2007 (UTC)
