Is the ETC proton gradient an example of secondary active transport? Why or why not?

And what is required for secondary active transport?

I suspect (but don't know for sure):
-A port of some kind (either symport or antiport)
-A substance going down it's concentration gradient through the port (that is somehow required to "bring along" the substance being transported by secondary active transport in either direction)
-Maybe ATP ----- Is ATP ALWAYS indirectly required, or can another substance or series of events indirectly power secondary active transport?

NO direct coupling of ATP
requires electrochemical potential difference which is created by ion pumps in/out

I think ETC is a form of primary active transport, due to redox coupling
