What happens with FADH2 donates its electrons to the electron transport chain and what are the final products?

Complex II is reduced and FADH2 is oxidized becoming FAD, the electrons continue down the electron transport chain providing the power to pump protons into the intermembrane space ( not as many protons as NADH because of the short delivery of FADH2 electrons to complex II ) where they fall down their concentration gradient through the synthase. Our electrons exit complex IV into the matrix where oxygen picks up two electrons and two protons forming water. 2H + 1/2O2 --> H2O.
