Wo ist die ATP-Synthase?
Die ATP-Synthase ist ein Enzymkomplex in der inneren Mitochondrienmembran, der ATP aus ADP und anorganischem Phosphat bildet.
Welche Arten der ATP Synthese gibt es?
Die 3 Arten der ATP-Synthese Es gibt zwei „moderne“, d.h. in der Evolution später entstandene, leistungsfähigere Arten der ATP-Synthese, die in speziellen Organellen ablaufen: die Photophosphorylierung in den Chloroplasten und die Atmungskettenphosphorylierung in den Mitochondrien.
What is the meaning of ATP synthase?
ATP Synthase Definition. ATP synthase is an enzyme that directly generates adenosine triphosphate (ATP) during the process of cellular respiration. ATP is the main energy molecule used in cells. ATP synthase forms ATP from adenosine diphosphate (ADP) and an inorganic phosphate (P i) through oxidative phosphorylation,
What is the difference between V-ATPase and FATP synthase?
Evolution. The F-ATP synthase displays high functional and mechanistic similarity to the V-ATPase. However, whereas the F-ATP synthase generates ATP by utilising a proton gradient, the V-ATPase generates a proton gradient at the expense of ATP, generating pH values of as low as 1.
How can the direction of ATP synthase be reversed?
The ATP synthase is freely reversible, and its direction depends on the thermodynamic balance between Δp and the matrix Δ Gp. Damage to the electron transport chain, increased proton leakage, or severe hypoxia can lower Δ p such that the ATP synthase reverses in the cell and starts to hydrolyse cytoplasmic ATP generated by glycolysis.
What is the molecular model of ATP synthase determined by crystallography?
Molecular model of ATP synthase determined by X-ray crystallography. Stator is not shown here. ATP synthase is a protein that catalyzes the formation of the energy storage molecule adenosine triphosphate (ATP) using adenosine diphosphate (ADP) and inorganic phosphate (P i ).
