Only under conditions where oxygen is limiting.  You understand what
"limiting" means?

Larger compared to what?  You'd have to specify the conditions you're
comparing them to -- what kind of organism, for instance.  I mean, you can
say an animal's respiratory system is all about bringing in a larger amount
of oxygen than it would get without a respiratory system.

Considering that the thermodynamics of the reactions involved are fixed, the
answer to that would have to be "no".  There are ways to short-circuit
oxidative phosphorylation such that energy would be wasted, but there are no
ways to get any extra energy out of it.
