In this work, we investigated the conformational changes of LHCSR1 induced by pH-sensing in the thylakoid lumen. WebbATP synthase uses this electrochemical gradient to make ATP, just like it did in cellular respiration. Note that a high concentration of protons = an acidic pH, so the thylakoid lumen has a much more acidic (lower) pH than the stroma. This whole process is quite analogous to the process that occurs during cellular respiration in the mitochondria.
Webb27 mars 2024 · The thylakoid membrane houses chlorophylls and different protein complexes, including photosystem I, photosystem II, and ATP ( adenosine triphosphate) synthase, which are specialized for light-dependent photosynthesis. When sunlight strikes the thylakoids, the light energy excites chlorophyll pigments, causing them to give up … Webb3 okt. 2024 · The thylakoid lumen is used for photophosphorylation during photosynthesis.

Webb11 aug. 1975 · The pH in the stroma and in the thylakoid space has been measured in a number of chloroplast preparations in the dark and in the light at 20 °C. Illumination … Webb9 apr. 2024 · The thylakoid structure comprises a simple thylakoid membrane creating an empty tubular space inside called thylakoid lumen. These thylakoids are stacked to form a cumulative structure called a granum. A granum looks like a stack of coins. These units are interconnected by thylakoids in the chloroplasts of higher plants.
Webb13 apr. 2024 · The number of thylakoid grana lamellae showed significantly lower in mesophyll cells than in exocarp cells, in both em41 and EMW, and it was further decreased in em41 (Fig. 3O, Table 3). These results suggest that a decreased number of chloroplasts, along with sparse thylakoids in giant chloroplasts, promote to the albinic phenotype of …

What three factors contribute to the formation of this large difference in … miss washington voy forumThe thylakoid lumen is a continuous aqueous phase enclosed by the thylakoid membrane. It plays an important role for photophosphorylation during photosynthesis. During the light-dependent reaction, protons are pumped across the thylakoid membrane into the lumen making it acidic down to pH 4. … Visa mer Thylakoids are membrane-bound compartments inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis. Thylakoids consist of a thylakoid membrane … Visa mer Chloroplasts develop from proplastids when seedlings emerge from the ground. Thylakoid formation requires light. In the plant embryo and in … Visa mer Thylakoids contain many integral and peripheral membrane proteins, as well as lumenal proteins. Recent proteomics studies of thylakoid fractions have provided further … Visa mer The word Thylakoid comes from the Greek word thylakos or θύλακος, meaning "sac" or "pouch". Thus, thylakoid means "sac-like" or "pouch-like". Visa mer Thylakoids are membrane-bound structures embedded in the chloroplast stroma.
