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?
There are two types:1) Alcohol Fermentation
2) Lactic Acid Fermentation
Fermentation
Alcoholic Fermentation
What is the name of the process that converts glucoseinto pyruvic acid?
GlycolysisWhat is the net gain in ATP for this process?
2 ATP
Glucose + 2ATP + 2NAD+ 2 Pyruvate + 2NADH + 4ATP
2 CO2 + 2 Ethyl Alcohol
Alcohol Fermentation
Besides alcohol what else is a waste product of alcoholic fermentation?
CO2
Yeast is a unicellular organism capable ofcarrying out alcoholicfermentation
Bakers Yeast
The CO2 that is releasedduring fermentation createsbubbles and pockets thatmake 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
What is the name of the process that converts glucoseinto pyruvic acid?
Glycolysis
What is the net gain in ATP for this process?
2 ATP
Glucose + 2ATP + 2NAD+ 2 Pyruvate + 2NADH + 4ATP
2 Lactic Acid
Lactic Acid Fermentation
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 ATP3) 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 Bacteria5) What organisms utilize lactic acid fermentation?
Bacteria & animal muscle ells when they run out of oxygen
