the outline of the theory suggests that movement of chemicals aross a membrane is used to generate energy in cells. When glucose is broken down in the cell hydrogen atoms (protons) are removed and added to carriers like NAD which become 'reduced'. these carriers are utilised in the mitochondria where a pH gradient is formed ( a larger concentation of protons on one side of the membrane than the other) protons flow across the membrane through an enzyme complex known as ATPase. which spins like a motor, it is not known precisely how this spinning action provides the energy to form the chemical bonds in ATP but is has been proven that it does!

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.
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 importance of chemiosmosis?
Chemiosmosis is crucial for ATP production in cellular respiration and photosynthesis. It involves the movement of protons across a membrane, creating an electrochemical gradient that drives ATP synthase to produce ATP, the primary energy currency of cells. This process is essential for various cellular functions, including metabolism, muscle contraction, and active transport. Without chemiosmosis, cells would be unable to efficiently harness energy from nutrients or sunlight.
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.
What comes out of the etc and chemiosmosis?
The electron transport chain (ETC) and chemiosmosis are critical processes in cellular respiration, specifically in the mitochondria. The ETC generates a proton gradient across the inner mitochondrial membrane by transferring electrons through a series of protein complexes, ultimately reducing oxygen to form water. This proton gradient drives ATP synthesis via ATP synthase during chemiosmosis, allowing for the production of ATP, the primary energy currency of the cell. In summary, the processes yield ATP and water as key products.
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.
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.
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 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.
Synthesis of ATP during light reactions?
Chemiosmosis
What role does ATP have in the electron transport chain?
ATP is produced as a result of the ETC and chemiosmosis.
The movement of protons during ATP production is called what?
The movement of protons during ATP production is called chemiosmosis. In this process, protons are pumped across a membrane, creating an electrochemical gradient that drives ATP synthesis.
Involves diffusion of hydrogen ions to make ATP?
Chemiosmosis.
Which of the following couples chemiosmosis to energy storage?
The coupling of chemiosmosis to energy storage occurs in the process of cellular respiration, specifically during oxidative phosphorylation in eukaryotic cells. This process involves the generation of a proton gradient across the inner mitochondrial membrane, which drives the synthesis of ATP by ATP synthase.
What does chemiosmosis produce and where does it happen?
it occurs in chloroplasts and mitochondria as well.
The relationship between ATP synthase and Chemiosmosis?
ATP synthase is an enzyme complex located in the inner mitochondrial membrane responsible for synthesizing ATP from ADP and inorganic phosphate during cellular respiration. Chemiosmosis is the process by which ATP synthase harnesses the energy stored in the proton gradient across the membrane to drive the phosphorylation of ADP to ATP. In essence, ATP synthase acts as a molecular turbine, using the energy from proton flow to catalyze the synthesis of ATP.
