ATP synthase functions by using the energy of the proton gradient established by the electron transport chain to synthesize ATP from ADP and inorganic phosphate.
It is composed of four major parts, the stator, the rotator, the internal rod, and the catalytic knob.
The intermembrane space has a higher concentration of protons. For the protons to move along their gradient, into the mitochondrial matrix, they enter a half channel in the stator, which is anchored to the membrane. The proton enters a binding site on the rotor and the binding of a new proton changes the shape of each subunit, making the rotor spin slightly (so that the next binding site is available).
Another proton which was previously binded is released as soon as a new proton is binded. This proton has already completed a full rotation on the rotor before travelling through another half channel leading to the mitochondrial matrix.
This spinning causes the internal rod to spin as well. The rod extends into the knob below it which is being held stationary by the stator. The turning of the rod causes catalytic sites on the knob to be activated. When an ADP and inorganic phosphate attach to the knob, they are joined to create ATP.
Three protons being binded to the rotator creates enough energy for one ATP to be synthesized.
What else can I help you with?
Which organelles contain functioning ATP synthetase complexes in their membranes?
The mitochondria and chloroplasts are organelles that contain functioning ATP synthetase complexes in their membranes. These complexes are responsible for producing ATP through oxidative phosphorylation in the mitochondria and photophosphorylation in the chloroplasts.
What enzyme is responsible for synthesizing ATP?
The enzyme is ATP synthase (sometimes referred to as "ATP synthetase").It catalyzes the synthesis of ATP from ADP and free inorganic phosphate. It is a remarkable enzyme, part of which spins round. In fact, ATP synthase has been called a molecular machine.To see an image, use the link below.
What is the purpose of the ATP and NADPH produced in the light reactions of photosynthesis?
ATP isn't created during the process of photosynthesis. Photosynthesis merely creates glucose, which is afterwards consumed to create the ATP. This ATP, however, serves the purpose all ATP does in the body: energy that the cell can use.
Chemiosmosis in the thylakoid membrane is directly responsible for?
Chemiosmosis in the thylakoid membrane is directly responsible for the generation of ATP during photosynthesis. It involves the movement of protons across the thylakoid membrane to create a proton gradient, which drives the synthesis of ATP by ATP synthase enzyme.
The purpose of cellular respiration is to create and use?
ATP (adenosine triphosphate), the main energy currency used by cells. It involves the breakdown of glucose or other fuel molecules to produce ATP through a series of metabolic reactions. The ATP generated is then used by the cell for various functions such as muscle contraction, transport of molecules, and other energy-requiring processes.
What drives the ATP synthetase to make ATP in respiration?
Protons.
What is the role of ATP synthetase in the light dependent reaction?
In the presence of ATP synthetase enzyme ADP is converted in to ATP by uniting one more phosphate bond, storing chemical energy.
What type of molecule is ATP synthetase?
ATP synthetase is an enzyme that is a type of molecular motor which facilitates the synthesis of ATP from ADP and inorganic phosphate during oxidative phosphorylation in mitochondria.
What is the enzyme required to make ATP?
ATP synthtase along with other enzymes and coenzymes .
Which organelles contain functioning ATP synthetase complexes in their membranes?
The mitochondria and chloroplasts are organelles that contain functioning ATP synthetase complexes in their membranes. These complexes are responsible for producing ATP through oxidative phosphorylation in the mitochondria and photophosphorylation in the chloroplasts.
What is the product of chemiosmoisis?
chemiosmosis is the method of ATP production in living organisms due to movement of hydrogen ions via proton protein pumps in a membrane. It involves the use of the enzyme ATP synthetase
What is the major functional difference between succinyl coenzyme A synthetase in plant and animal cell mitochondria?
Succinyl co-enzyme A synthetase in Plants produces ATP while in case Animals It produces GTP (Imran Farooqui) mail me at :- imranfarooqui009@gmail.com
What is the difference between ATP synthesis and ATP synthase?
synthases do not use energy from NTP's, sythetases do! synthase can be used with any enzyme that catalyzes synthesis (whether or not it uses nucleoside triphosphates), whereas synthetase is to be used synonymously with 'ligase'.
How many ATP is produce in liver cell for beta oxidation?
21.5 1 nadh x 2.5 2 fadh2 x 1.5 6 nadh x 2.5 2 gtp that;s 22.5 ATP. subtract 1 ATP equivalent for succinyl coa synthetase, and you get 21.5 ATP.
What does hydrogen ions bind to during ATP Synthetase?
Hydrogen ions bind to the F0 subunit of ATP synthase during ATP synthesis. This binding causes the rotation of the ATP synthase complex, leading to the synthesis of ATP from ADP and inorganic phosphate.
What is the purpose of atp in your bodies?
It is energy source
