abb0t · Answer

NAD$^+$

alphadxg · Answer

NAD+ is the answer.

FADH2 is also a electron carrier, but it carriers electrons through Complex II of the hydrogen gradient. NAD+ is the main carrier, because it will produce more ATP because it goes through Complex I through the end of Complex IV.

alphadxg · Answer

^^^ as a result it will produce the hydrogen gradient which will drive ATP synthases.

I don't know if I would call it the main carrier, after all both are required.  If either is not present the process cannot take place.  Though, it is true that NADH<-->NAD+ H+ is done in more places and in high numbers at individual places.  Places in the metabolic pathway that is.
