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.
What else can I help you with?
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 is the relationship between chemiosmosis and ATP formation?
chemiosmosis is one of the processes that produces ATP. this happens in the inner membrane of the mitochondria.
Does chemiosmosis expend energy?
No, chemiosmosis does not expend energy. Instead, it utilizes the energy stored in the form of a proton gradient to drive ATP synthesis in processes such as oxidative phosphorylation in mitochondria or photosynthesis in chloroplasts.
What protein is involved in chemiosmosis?
ATP synthase
What couples chemiosmosis to energy storage ATP synthase cytochromes FADH2 NADH or electron transport?
ATP synthase couples chemiosmosis to energy storage.
What does chemiosmosis produce and where does it happen?
it occurs in chloroplasts and mitochondria as well.
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.
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.
Synthesis of ATP during light reactions?
Chemiosmosis
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.
Involves diffusion of hydrogen ions to make ATP?
Chemiosmosis.
What does NADH carry that can be used in the process of chemiosmosis?
NADH carries high-energy electrons that can be used in the process of chemiosmosis to create a proton gradient across the inner mitochondrial membrane. This proton gradient is then used to generate ATP through ATP synthase.
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.
