Aim #39: 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) What is another word for anaerobic
respiration?
Fermentation
There are two types:
1) Alcohol Fermentation
2) Lactic Acid Fermentation
Alcoholic Fermentation
Glucose + 2ATP + 2NAD+  2 Pyruvate + 2NADH + 4ATP
Alcohol Fermentation
2 CO2 + 2 Ethyl Alcohol
What is the name of the process that converts glucose
into pyruvic acid?
Glycolysis
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 our cells carry out
anaerobic cell respiration?
Yes, when our
muscles run out of
oxygen they do
lactic acid
fermentation
8) Lactic Acid Fermentation
Glucose + 2ATP + 2NAD+  2 Pyruvate + 2NADH + 4ATP
Lactic Acid Fermentation
2 Lactic Acid
What is the name of the process that converts glucose
into pyruvic acid?
Glycolysis
What is the net gain in ATP for this process?
2 ATP
Let’s work out & feel the burn
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 Acid Fermentation
Review
1) What is the organic compound used by both?
Glucose
2) What is their main product?
2 ATP
3) How are they different?
Alcohol fermentation produces alcohol & carbon dioxide
and lactic acid fermentation produces lactic acid
4) What organisms utilize alcohol fermentation?
Yeast and Bacteria
5) What organisms utilize lactic acid fermentation?
Bacteria & animal muscle ells when they run out of oxygen
