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.

Does chemiosmosis involve a concentration gradient?

Yes, chemiosmosis involves the movement of ions across a membrane from an area of high concentration to an area of low concentration, creating a concentration gradient. This gradient drives the production of ATP in processes such as oxidative phosphorylation during cellular respiration.


What is location of ETC and chemiosmosis in photosynthesis and cellular respiration?

In photosynthesis, ETC and chemiosmosis occur in the thylakoid membranes of chloroplasts. In cellular respiration, these processes take place in the inner mitochondrial membrane. These locations are where the electron transport chain (ETC) pumps protons across the membrane, creating a proton gradient that drives ATP production through chemiosmosis.


What protein enzyme is involved in chemiosmosis?

ATP synthase is the protein enzyme involved in chemiosmosis. It is responsible for generating ATP by facilitating the movement of protons across the inner mitochondrial membrane.


Why does chemiosmosis require a membrane?

Chemiosmosis involves the movement of ions across a membrane, which creates an electrochemical gradient that drives ATP synthesis. The membrane is necessary to separate the high and low concentration of ions, allowing for the generation of the proton gradient that powers ATP production.


How much ATP does chemiosmosis and the kerbs cycle produce?

The chemiosmosis process through oxidative phosphorylation can generate up to 34 ATP molecules from one glucose molecule. The Krebs cycle, on the other hand, produces 2 ATP molecules per glucose molecule.

What happens during chemiosmosis?

During chemiosmosis, protons are pumped across the inner mitochondrial membrane, creating a proton gradient. The protons then flow back through ATP synthase, driving the synthesis of ATP from ADP and inorganic phosphate. This process is a key step in oxidative phosphorylation, the process by which cells generate ATP using energy derived from the electron transport chain.
