Homework Answers
Reduction potential of NAD+ is - 0.32 and that of FAD+ is - 0.22
Since reduction potential of FAD+ is high, it has more tendency to reduce or act as stronger Oxidizing agent than NAD+. Thus, when Succinate dehyrogenase release electron, FAD+ accept electron (because it has greater tendency to gain electron) and reduced to FADH2.

Which of the following could explain why transfer of electrons from FADH2 to Coenzyme Q (CoQ) is not coupled to proton transfer, but transfer from NADH to Coenzyme Q is? Select one: a. FADH2 donates more electrons than NADH to the electron transport chain. b. Because FADH2 has higher affinity for electrons than Coenzyme Q c. Because FADH2 is a higher energy carrier than NADH d. Because the transfer of electrons from FADH2 to CoQ does not release enough energy....
