Anaerobic Respiration:

“Oxidation without Molecular Oxygen”

(Is this an Oxi(gen)-Moron?)

C6H12O6 ATP

Pyruvate With O2

Mitochondria: Oxidative

Phosphorylation

NADH H

Bucket O’ NAD+

Where does the NAD+ come from?What would happen if the bucket was empty?

Questions

How does the bucket normally stay full?

2. Fermentation allows NADH to recycle to NAD in order to continue to make ATP without oxygen

O2

1. NADH (energy rich) can be used to convert pyruvate into another molecule

3. ATP can still be made as long as the pyruvate is “going somewhere”

NAD

1. Lactic Acid

2. Ethyl Alcohol + CO2

Lactic Acid Fermentation(Muscle cells, Bacteria)

Alcoholic Fermentation (Bacteria, Yeasts)

3. Acetic Acid (vinegar) + CO2

(Bacteria)

Without O2 all that is left is NADH, Pyruvate, and Glucose with nowhere to go.

Why Cells Do “Fermentation”Types of Fermentation A

Shakespeare

1. “Glucose is really the ultimate tragic hero…. Hamlet would have been proud”2. “Its hard to save the Princess underground. Not having oxygen for your ETC

is like trying to fix a plugged up sewer”3. “Your lactic acid is your opponent’s best friend”4. “My cycle is the cycle of life, and the cycle of death”5. “Wow!!! My food really does come out my nose”6. “You will never have a Miller time unless the NADH is invited first”7. “You think I’m hot now, wait until my mitochondrial membranes start leaking”8. “They told the Twinkie don’t come around here Don’t wanna see your face, you better disappear The fire’s in the Kreb’s, and the enzymes are really clear, So eat it…..just eat it Just eat it…eat it Just eat it…eat it” 9. “Stay away from Coenzyme A, it’s a very bad friend”
