In which process electrons stored in the form of reduced coenzyme (NADH & FADH2) are passed through 

an elaborate and highly organized chain of proteins and coenzymes. Then, they finally reach the 

molecular oxygen (terminal acceptor of electrons) with the generation of energy (ATP

Fatty acids are a component of fats but have a distinct chemical difference apart from fats that would allow them to travel fairly freely in the aqueous environment of the bloodstream. They don’t, however, and are transported with serum albumin. What about the chemistry of fatty acids makes it so that it might not be good to have a lot of them traveling freely in the bloodstream?
