Where does the electron transport chain occur within the mitochondria?

• In the cytosol

• In the inner membrane

• In the mitochondrial matrix

• In the outer membrane

What is the role of NADH and FADH2 in the electron transport chain?

• They donate electrons to the chain

• They act as final electron acceptors

• They transport ATP
