Question

Describe the mechanism by which ATP synthase makes ATP.
Protons flow with their
concentration gradient
into a half-channel in
subunit a.
Protons neutralize a
glutamine residue in the
center of a c-subunit,
allowing it to enter the
membrane.
As one c-subunit enters
the hydrophobic interior
of the membrane, another
exits and releases a proton
through the second half-
channel in subunit a into
the mitochondrial matrix.
Rotation of the c-ring
rotates the attached alpha
subunit.
When the beta subunit is
in the loose conformation,
it may contain ATP.
When the beta subunit is
in the open conformation,
ADP/Pi and ATP are able
to diffuse freely in and out
of the active site.
When the beta subunit
moves to the tight
conformation, ADP and Pi
are squeezed together to
make ATP.
