Electron Transport Chain
-the electron transport chain is the last part of
cellular respiration where the most ATP is
produced and occurs in the membrane of the
mitochondria -the electron transport chain
utilizes all the NADH and FADH2 produced earlier
and O2 is used, and H2O is produced
2
Electron Transport Chain
-the basics of the electron chain involve using
NADH and FADH2 to move electrons through proteins
in the membrane -this movement of electrons pumps
H ions from the intermembrane space into the
matrix -during this process, O2 is used and H2O
is produced

Electron Transport Chain
-eventually, those H ions return to where they
came from through a molecular motor known as ATP
synthase which produces a lot of ATP

Electron Transport Chain Review
Use these review questions to see how much you
remember from todays lesson 1. What chemicals
are involved in the electron transport chain?
What is used up and what is made as a result? 2.
What happens with the H ions? Where do they go
as electrons are transported through the
proteins? 3. What happens to all the H ions at
the end of the electron transport chain? 4.
Where is all the ATP created in this whole
process?
