What is the relationship between the electron carriers NADH and FADH and the electron transport chain?
_________________________________________________________________________________________________________________________
_________________________________________________________________________________________________________________________
Explain the movement of the electrons down the transport chain include: where the electrons come from,
what happens to their energy level as they move down the electron transport chain and what happens to
them when they reach the bottom.
