Homework Answers
C. (C). Option is correct.
This is because as electrons are transfered from NADH+H+ and FADH2 to electron transport system proteins, the ETS proteins transfer electrons in a series of decreasing oxidation potential in ETS chain. During this process , the H+ gradient is created which is used as a driving force for the formation of ATP with the help of ATP synthase enzyme. Thus happens due to conformational change in the enzyme die to H+ transfer from intermembrane space to mitochondrial matrix while breaking the conc. Gradient.
