WebbHow do you suppose the pH of the solution in the thylakoid space compares with the pH of the solution in the stroma? what is responsible for the difference? Expert Answer 100% (1 rating) Chemiosmosis: It is the movement of ions down their electrochemical gradient across a selective permeable membrane. WebbThe thylakoid space will have a lower pH (more acidic) when there is a high concentration of H+ present. What three factors contribute to the formation of this large difference in … The 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. A stack of thylakoids is called a granum and resembles a stack of coins. Membrane Visa mer Thylakoids can be purified from plant cells using a combination of differential and gradient centrifugation. Disruption of isolated thylakoids, … Visa mer The thylakoids are the site of the light-dependent reactions of photosynthesis.
