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

Let’s make some wine!

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
