Oxidative Phosphorylation: ATP Synthase Flashcards
Where is F1 located?
In the mitochondrial matrix
Where is F0 located?
In the inner mitochondrial membrane (transmembrane protein)
Which subunit of ATP synthase contains the catalytic activity of the synthase?
F1
Which subunits of F1 make up the bulk of F1? How are they arranged?
The three alpha and beta subunits. They are arranged alternately in a ring.
Where are the active sites on the alpha3beta3 rings?
On the beta subunits
What connects the gamma and epsilon subunits?
stalk
True or false: Each of the beta subunits of F1 is distinct because each interacts with a different face ofthe gamma subunit.
True
Which subunit of ATP synthase contains the proton channel of the complex?
F0
What reaction does ATP synthase catalyze?
The synthesis of ATP and H20 from ADP, orthophosphate, and a proton.
What causes the active sites on ATP synthase to change function?
The proton motive force
