WebDuring the light-dependent reaction, protons are pumped across the thylakoid membrane into the lumen making it acidic down to pH 4. Granum and stroma lamellae [ edit] In higher plants thylakoids are organized into a granum-stroma membrane assembly. A granum (plural grana) is a stack of thylakoid discs. Chloroplasts can have from 10 to 100 grana.

WebAug 25, 2024 · What is the pH difference between the thylakoid space and the stroma? During photosynthesis, the lumen becomes acidic, as low as pH 4, compared to pH 8 in the stroma. This represents a 10,000 fold concentration gradient for protons across the thylakoid membrane. 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.
