ATP synthase is a multisubunit complex with four main parts, each made up of multiple polypeptides. Protons move one by one into binding sites on one of the parts, causing it to spin in a way that catalyzes ATP production from ADP and inorganic phosphate. The flow of protons behaves somewhat like a rushing stream that turns a waterwheel. ATP synthase is the smallest molecular rotary motor known in nature.
What else can I help you with?
Where are parts of the chloroplast ATP synthase located that are involved in the phosphorylation of ADP to ATP?
The parts of the chloroplast ATP synthase involved in the phosphorylation of ADP to ATP are located in the F1 complex, particularly on the beta subunits. These subunits contain catalytic sites that bind ADP and inorganic phosphate to facilitate ATP synthesis through a series of conformational changes and proton flow driven by the proton gradient across the thylakoid membrane.
Is ATP synthase a protein?
Yes, ATP synthase is a protein.
Is ATP synthase an integral protein?
Yes, ATP synthase is an integral protein.
In the presence of a metabolic poison that specifically and completely inhibits the function of mitochondrial ATP synthase what would you expect A. a decrease in the pH difference ac?
In the presence of a metabolic poison that inhibits mitochondrial ATP synthase, the pH difference across the mitochondrial membrane would increase. This is because ATP synthase plays a crucial role in generating ATP by utilizing the proton gradient (pH difference) across the membrane. Inhibition of ATP synthase would disrupt ATP production, leading to a buildup of protons on one side of the membrane.
What structure that is found in the thylakoid membrane is important to chemiosmosis?
ATP synthase is the structure found in the thylakoid membrane that is important for chemiosmosis. It is responsible for generating ATP by utilizing the proton gradient created during the photosynthetic electron transport chain.
Which of the following is false about the structure and function of ATP synthase?
At least 10 protons pass through ATP synthase in order to make a molecule of ATP.
Where are parts of the chloroplast ATP synthase located that are involved in the phosphorylation of ADP to ATP?
The parts of the chloroplast ATP synthase involved in the phosphorylation of ADP to ATP are located in the F1 complex, particularly on the beta subunits. These subunits contain catalytic sites that bind ADP and inorganic phosphate to facilitate ATP synthesis through a series of conformational changes and proton flow driven by the proton gradient across the thylakoid membrane.
Where does ATP synthase perform its function?
Within an organelle called the mitochondrion (plural mitochondria), which are scattered throughout the cell.
What has the author Yongbiao Xue written?
Yongbiao Xue has written: 'Molecular biology of genes encoding subunits of the mitochondrial F0F1-ATP synthase complex in cytoplasmic male sterileand male fertile sugar beet (Beta vulgaris L.)'
Is ATP synthase a protein?
Yes, ATP synthase is a protein.
Is ATP synthase an integral protein?
Yes, ATP synthase is an integral protein.
Why is it important that a membrane separate the cellular regions on either side of an ATP synthase molecule in order for the protein to perform its function?
A membrane separation is crucial for ATP synthase to establish a proton gradient across the membrane. This gradient serves as the driving force for ATP synthesis as protons flow through the ATP synthase from high to low concentration. Without this separation, the necessary proton gradient cannot be generated.

Inhibition of ATP synthase would disrupt ATP production, leading to a buildup of protons on one side of the membrane.
When ATP synthase in activated it adds a phosphate group to what molecule?
ATP synthase catalyzes the addition of a phosphate group to an ADP molecule. ADP + ATP synthase + P --> ATP + ATP synthase (ATP synthase on both sides of the equation indicates that, as an enzyme, it is not used up in the reaction.)
What has the author Terese Easton written?
Terese Easton has written: 'The role of nitric oxide synthase in platelet membrane function in dyslexic adults compared to controls'
Where are the catalytic knobs of ATP synthase located?
The catalytic knobs of ATP synthase would be located on the stromal side of the membrane. Protons travel through ATP synthase from the thylakoid space to the stroma.
What is the name and function of the protein channel where hydrogen ions escape into the matrix of the mitochondrion?
The protein channel is called ATP synthase. It functions in the mitochondrion by allowing hydrogen ions to flow back into the matrix through the channel, which generates ATP in the process known as oxidative phosphorylation.
