Cellular Respiration:
• Chemical bond energy in food molecules is
converted to a form usable by organisms
• Energy is stored in the bonds of ATP
(adenosine triphosphate)

Aim: How do living things
accomplish anaerobic
respiration?
1) What do all living things do to
acquire energy?
To get
2) What is Anaerobic Respiration?
ENERGY
Organisms make ATP (energy) without oxygen.
3) This process is also called fermentation.
There are two types of anaerobic respiration:
Alcoholic Fermentation
4) What is the name of the first step that breaks down
glucose?
Glycolysis
5) What is the chemical reaction?
Glucose  Alcohol+ 2CO2 + 2ATP
6) What is the net gain in ATP for this process?
2 ATP
Let’s make some wine!
Besides alcohol what else is a
waste product of alcoholic
fermentation?
CO2
Yeast is a unicellular
organism capable of
carrying out alcoholic
fermentation
Bakers Yeast
The CO2 that is released
during fermentation creates
bubbles and pockets that
make bread rise.
7) Can we do anaerobic cell
respiration?
Yes, when our
muscles run out of
oxygen they do
lactic acid
fermentation
Lactic Acid Fermentation
What is the name of the first step that breaks down glucose?
Glycolysis
8) What is the chemical reaction?
Glucose  2 Lactic Acid + 2 ATP
What is the net gain in ATP for this process?
2 ATP
Glucose has 90 x the energy of
ATP
1 Glucose = 2 ATP
The rest is lost as heat
& remains in alcohol
or lactic acid
Types of Anaerobic cell
respiration
• Alcohol fermentation
• Glucose
2 ATP + 2CO2 +
Alcohol
• Lactic acid fermentation
• Glucose
2 ATP + Lactic acid
Why do bread and Swiss cheese
have so many holes?
Alcohol fermentation vs Lactic A. Fermentation

•
•
•
•
•
•
•
•
What is the organic compound used by both?
Glucose
What is their main product?
2 ATP
How are they different?
Alcohol fermentation produces alcohol & carbon
dioxide and lactic acid fermentation produces lactic acid
What organisms utilize alcohol fermentation?
Yeast and Bacteria
What organisms utilize lactic acid fermentation?
Bacteria & Animal muscle cells when they run out of
oxygen
• Where does the energy
come from to change
ADP to ATP?
– From food (glucose)
during cellular
respiration
• What is the energy
used for when ATP is
changed to ADP?
– To perform life
functions
• What process is shown
in the setup?
– Cellular respiration?
• What gas is being
produced by the yeast?
– Carbon dioxide
