The driving force of ATP Synthesis at the location of athe ATP synthesis complex is the ________.

1. proton motive force
2. hydrolysis of ATP
3. phosphorylation of ADP
4. proton concentration gradient

I believe the answer is "1" because pmf is the driving force of ATP when ADP and Pi come together to form ATP. Not sure though, please help.


You can check alternatives by searching using each as key words. This is what I found for "proton motive force":

In the future — to get the information more quickly — you could do similar searches.

I hope this helps. Thanks for asking.
