Chapter 6, Problem 4CT

As you learned in this chapter, cell membranes arc required for electron transfer phosphorylation. Thylakoid membranes in chloroplasts serve this purpose in photosynthetic eukaryotes. Prokaryotic cells do not have this organelle, but many are photosynthesizers. How do you think they carry out the light-dependent reactions, given that they have no chloroplasts?

After electrons are raised to high energy levels in photosystem II, they travel down an electron transport chain.  As they are stepped down in energy, the lost energy is used to power which process.      The pumping of high energy electrons into the intermembrane space.  This creates a large difference in concentration and in electric charge between the intermembrane space and the lumen of the thylakoid.  When these high energy electrons rush back into the thylakoid lumen, they are forced to travel through one of the ATP synthase molecules that sits embedded in the thylakoid membrane.  ATP synthase uses the flow of hydrogen ions to phosphorylate ADP, converting it to ATP.     The pumping of hydrogen ions into the stroma.  This creates a large difference in concentration and in electric charge between the stroma and the lumen (watery interior) of the thylakoid.  When When the hydrogen ions in the stroma rush back into the thylakoid lumen, they are forced to…
In 2005, a new species of green sulfur bacteria was discovered near a geothermal vent at the bottom of the ocean. An exceptionally efficient light-harvesting mechanism allows these bacteria to carry out photosynthesis where the only illumination is a dim volcanic glow emanating from the vent. Cell membrane are required for electron transfer chains in the light-dependent reactions. but these bacteria have no internal membranes. How do you think they carry out the light-dependent reactions?
