Where does the synthesis of ATP by chemiosmosis occur?
The generation of ATP by chemiosmosis occurs in mitochondria and chloroplasts, as well as in most bacteria and archaea, an electron transport chain pumps H+ ions (protons) in the thylakoid spaces through thylakoid membranes to stroma (fluid).
How is ATP synthesized during chemiosmosis?
Chemiosmosis: In oxidative phosphorylation, the hydrogen ion gradient formed by the electron transport chain is used by ATP synthase to form ATP. The turning of this molecular machine harnesses the potential energy stored in the hydrogen ion gradient to add a phosphate to ADP, forming ATP.
Where is ATP synthesized located?
mitochondria
ATP is synthesized from its precursor, ADP, by ATP synthases. These enzymes are found in the cristae and the inner membrane of mitochondria, the thylakoid membrane of chloroplasts, and the plasma membrane of bacteria [5]. Usually, there is a general understanding that ATP generation occurs in mitochondria.
Where does the chemiosmosis take place?
Where does chemiosmosis occur? In eukaryotes, it occurs in the mitochondria during cellular respiration and in the chloroplasts during photosynthesis. Prokaryotes lack these organelles and therefore chemiosmosis will occur in their cell membrane.
How many ATP is produced in chemiosmosis?
Most biochemists agree that 36 molecules of ATP can be produced for each glucose molecule during cellular respiration as a result of the Krebs cycle reactions, the electron transport system, and chemiosmosis. Also, two ATP molecules are produced through glycolysis, so the net yield is 38 molecules of ATP.
Where does the Chemiosmosis take place?
What are the products of chemiosmosis?
Chemiosmosis is involved in the production of adenosine triphosphate (ATP), which is the main molecule used for energy by the cell. In eukaryotes, ATP is produced through the process of cellular respiration in the mitochondria.
How is ATP synthesized 10?
ATP is synthesized from ADP and Pi. The reaction is catalyzed by an enzyme called as ATP synthase. When the enzyme and substrate (ADP) are distant inside the cell, the reaction cannot take place spontaneously.
What are the two ways that ATP is synthesized?
The two ATP-producing processes can be viewed as glycolysis (the anaerobic part) followed by aerobic respiration (the oxygen-requiring part).
How many ATP molecules are produced in chemiosmosis?
What step produces the most ATP?
The stage of cellular respiration that produces the most ATP is electron transport chain. Glycolysis , Krebs cycle , and Fermentation produce ATP but not more than Electron Transport Chain.
How is ATP involved in chemiosmosis?
ATP synthase is the enzyme that makes ATP by chemiosmosis. It allows protons to pass through the membrane using the kinetic energy to phosphorylate ADP making ATP. The generation of ATP by chemiosmosis occurs in chloroplasts and mitochondria as well as in some bacteria.
Which organelle does the process of ATP synthesis occur?
The majority of cellular ATP is synthesized during cellular respiration in the mitochondria of animal and plant cells, and during photosynthesis in the chloroplasts of plant and algal cells. The mechanism of ATP synthesis in these two organelles is very similar and represents an evolutionarily conserved mechanism (which bacteria also employ).
Is ATP synthesized within mitochondria?
In mitochondria, eubacteria and chloroplasts , the synthesis of ATP is made by a complex molecular machine known as ATP synthase.
