Which vitamins are NADH and FADH2 respectively formed from?

Explain how the electrons, which have reduced coenzymes, are delivered to the electron transport chain and how they are transported to oxygen.

In what form is the energy stored as, when the electrons are passed through the chain.

Explain how the energy generated by the electron transport chain
is coupled to the formation of ATP by oxidative phosphorylation.

Solutions

Expert Solution

For each pair of electron flow from NADH to O2 ,a total of 10 protons are translocated to the inner membrane space of mitochondria. This form an electrochemical gradient. The energy stored in such a gradient, termed the proton motive force used to make ATP.
