When acetyl-CoA joins with 4C
oxaloacetate, what is formed?
(6C) citrate/citric acid
Where in the mitochondrion
does the Kreb’s Cycle occur?
•matrix
For one glucose, how many turns of
the Citric Acid Cycle are taken?
•two (2)
How many ATP’s are made in the
Kreb’s Cycle? (per one glucose)
•two (2)

What is done to the NAD+’s
in the Kreb’s Cycle?
“They are _____.”
•reduced
What is the other electron
acceptor in the citric acid cycle?
•FAD
When the FAD is reduced, what
does it become?

Where is the electron transport chain located?
embedded in inner membrane
(of mitochondrion)
What molecule(s) deliver electrons
to ETC?
