• Where will the NADH
• produced in this
• reaction go next
• if oxygen is
• present?
• Where will the pyruvic acid gonext if oxygen is
  present?

To electron transport chain
Into mitochondria and Krebs cycle
3

• Where does this
• reaction happen?
• Where will the pyruvic acid gonext if oxygen is
  NOT present?

In the cytoplasm
Stays in cytoplasm and does fermentation
4
What happens to the CO2 produced in
this reaction? Acetyl-CoA will join next
with a 4 carbon molecule to make __________
Released into atmosphere when we exhale
Citric acid
5
Which ion is being pumped across the membrane at
the purple arrows during electron transport ?
6
Where will the citric acid that is produced here
go next? What will happen to the Cs in citric
acid that came from Acetyl-CoA?
Cycle through the Krebs cycle
Released into atmosphere as CO2
7
Where does the FADH2 produced here go
next? Where does the ATP produced here go?
to the Electron transport chain
Used by cell for cellular activities
8
What reaction happens on the matrix side of
the membrane when ATP synthase spins?
A phosphate is added to ADP to make ATP
9
Name the 6 carbon molecule formed in this
reaction What happens to the Coenzyme A after
dropping off its 2 carbons?
Citric acid
Recycles back and picks up 2 more carbons from
pyruvic acid
10

CO2, NADH, FADH2, ATP
11
Where does the CO2 produced here go next?
released to the atmosphere
12
O2
Which molecule acts as the last electron acceptor
to make water?
