The final stage of ATP synthesis
is the creation of ATP. ATP synthase uses the energy from a proton
gradient to combine ADP and Pi into an ATP molecule. Clicking
on each of the thumbnail images will bring up a larger, labeled
version of the described scene.
see the Flash movie for the following sequence of images,
The lower portion of the ATP
synthase complex combines ADP and Pi to synthesize ATP.
In biolgical systems a proton gradient
is maintained by the electron transport chain. In our example,
however, the ETC is not functional. The proton gradient has
equalized, and there is no energy left to synthesize more
