Talk:Chloroplast membrane

Merge with thylakoid since only chloroplasts have the thylakoid membrane?--nixie 01:44, 17 Oct 2004 (UTC)

er.. chloroplasts have more than just thylakoid membranes, hence why there is an article about them. Joe D 02:36, 17 Oct 2004 (UTC)

Of course they do. I think a better entry would be about chloroplast membranes and include the thylakoid entry- otherwise there is too much redundancy between articles.--nixie 02:39, 17 Oct 2004 (UTC)

Does everyone concur with the current "widely accepted" concept of endosymbiosis and chloroplasts?

Hydrogen ions are H+ not H-. And the pH scale only goes up to 14, not 15 as shown in the article. However I do not know the pH value of the thylakoid innermembranous space so I will not change the value shown. Also a thousand-fold difference from pH 7 would be pH 10. Plus, the CO6.... equals glucose is rubbish. [User: djc biology teacher] 11:38, 3 February 2007

Thylakoid membrane

This is confusing: "...travel down the electron transport chain. This exergonic fall in potential energy along the way is used to draw (not pump!) H+ ions from the lumen of the thylakoid into the cytosol of a cyanobacterium or the stroma of a chloroplast. A steep H+ gradient is formed, which allows chemiosmosis to occur"

If so, then how is the pH of the thylakoid lumen more acid than the stroma, as mentoined in the next paragraph? My understaning is that the photoelectron transport chain pumps protons from the stroma into the thylakoid lumen, acidifying it. ATP synthase allows the protons to escape from the thylakoid back into the stroma, coupled to ATP synthesis. Eaberry (talk) 22:59, 6 October 2025 (UTC)
