Cells often use an electron transport chain to separate electrons from hydrogen protons. The hydrogen protons are then used during chemiosmosis. A hydrogen ion gradient is formed and the hydrogen ions flow through the ATP synthetase molecule to the other side of the membrane. Hydrogen ions accumulate outside the inner mitochondrial membrane during cell respiration and in the inner membrane space of the thylakoid membrane of chloroplasts during photosynthesis. Bacteria use the outside plasma membrane as the surface to build up the hydrogen ion gradient. Therefore the energy from food is transferred to hydrogen ions, and the hydrogen ions transfer the energy to ATP via the ATP synthetase enzyme. In this discussion you should include a discussion of the solar powered purple proton pump and the information found in Figures 6-10, 6-11, 6-12, 6-A, and 8-12 (p. 169). Chemiosmosis is critical in ATP production in eukaryote cells as well as most prokaryote cells.
Chemiosmosis, the diffusion of hydrogen ions on a selectively permeable membrane.
Yes, chemiosmosis involves a concentration gradient. Think of chemiOSMOSIS, osmosis being the diffusion of water, which involves a concentration gradient.
etc takes place in mitochondria while chemiosmosis takes place entirely in cell membrane
Chemiosmosis involves the pumping of protons through special channels in the membranes of mitochondria from the inner to the outer compartment. The pumping establishes a proton gradient
ATP synthase
ATP is the product of the process known as chemiosmosis! =]
Does chemiosmosis expend energy
Chemiosmosis, the diffusion of hydrogen ions on a selectively permeable membrane.
Yes, chemiosmosis involves a concentration gradient. Think of chemiOSMOSIS, osmosis being the diffusion of water, which involves a concentration gradient.
it creates a concentration gradient allowing for chemiosmosis
NADH carries hydrogen and electrons that can be used in the process of chemiosmosis.
ATP synthase couples chemiosmosis to energy storage.
chemiosmosis is one of the processes that produces ATP. this happens in the inner membrane of the mitochondria
chemiosmosis is one of the processes that produces ATP. this happens in the inner membrane of the mitochondria.
it occurs in chloroplasts and mitochondria as well.
