Initially, the stroma was thought to simply provide support for the pigmented thylakoids.
WebNov 19, 2009 · On the pH scale, the neutral point is 7, and acids have pH lower than 7. So the higher the acid concentration, the lower the pH will be. Is the pH of a strong acid higher or lower than the... Web1 Answer. Energy from an electron transport chain is used to actively transport protons from the stroma to the thylakoid lumen. Thus the lumen has a relatively higher proton concentration and therefore a lower pH than the stroma. Higher [H +] means lower pH. …
WebJun 25, 2004 · Stromal pH somewhat depends on external pH as well as on proton uptake by thylakoids in the light. The light-induced stromal alkalization is quickly reversed in the dark as protons passively diffuse across the membrane from the thylakoid lumen. WebDec 1, 2024 · Stroma is the liquidus material found throughout the cavity of the chloroplast. It is where the light-independent reaction process of photosynthesis takes place.
