Ph in thylakoid space
Webb6 mars 2024 · In oxidative phosphorylation, the energy comes from electrons produced by oxidation of biological molecules. In photosynthesis, the energy comes from the light of the sun. Photons from the sun interact with chlorophyll molecules in reaction centers in the chloroplasts (Figures 5.3. 1 and 5.3. 2) of plants or membranes of photosynthetic … Webb1 Answer Sorted by: 4 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 …

When sunlight strikes the thylakoids, the light energy excites chlorophyll pigments, causing them to give up … duth theseis ergasiasWebbImagine that a researcher has developed a way to isolate thylakoids from chloroplasts and to make the pH of the thylakoid space acidic.If these isolated thylakoids are transferred to a pH8 solution in the dark,what might the researcher expect to observe? 10+ million students use Quizplus to study and prepare for their homework, quizzes and ... in a reaction c+co2 2coWebbATP 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. in a reaction a+b product rate is doubledWebbEnergy travels through the electron transport chain, which pumps hydrogen ions into the thylakoid space. This forms an electrochemical gradient. The ions flow through ATP synthase from the thylakoid space into the stroma in a process called chemiosmosis to form molecules of ATP, which are used for the formation of sugar molecules in the … duth swWebbSee Answer. Question: During the daylight, what might you observe in chloroplasts? a. Reduced rates of ATP synthesis b. A decrease in the pH in the thylakoid space C. An increase in the pH within the stroma d.
