Okay…some basics:
Write this down 100,000 times:
ALL LIVING THINGS UNDERGO SOME FORM
OF CELLULAR RESPIRATION.
But WHAT, you ask, is ATP?
(I knew you’d ask!)
ATP = Adenosine TriPhosphate
ATP is just like MONEY for our
bodies. We need it to do
everything….even dumb looks you
give your teacher!
The ATP-ADP CycleCould this be more exciting?
The energy from ATP comes from the chemical bond between the last two phosphates.
ATP is broken into ______ and a free __________. This gives off ______!
ADPphosphate
energy
What do WE need to make energy?

What do Humans need to make energy?
AND
Respiration Song…Yup…you heard it here!
The (General) Formula for Aerobic Respiration
There is ONE type of cellular respiration and TWO types of fermentation (these two will be covered in a few more slides!):
OR
The Not-So-Exciting-But-Really-Accurate Video
Glucose + Oxygen Carbon Dioxide + Water + Energyenzymes
C6H12O6 + O2 CO2 + H2O + 36 ATPenzymes
Hmm…Is it really that simple?
Of course it isn’t! Don’t fall for her
tricks!!
The REAL scoop….
1. ALL types of respiration/fermentation start with a process called GLYCOLYSIS.
2. Glyco=Glucose, Lysis=Split
Glucose + 2 ATP 4 ATP + 2 Pyruvic Acid
3. THEN…Pyruvic Acids are plugged into a second formula based on the types of enzymes present and whether or not oxygen is available.
We now interrupt your notes for a silly analogy…
Aunt Mabel had altercation with the police and mysteriously
disappeared…
The very next day…The 3 Stooges come into Money
Part I: Their initial investment strategy…
GlycoBank:
$100 gets turned into 2 $50 bills and
$4 interest
(really only a net gain of $2 after the
initial $2 service charge for opening
a new account)
Moe’s brilliant plan!
Mrs. Krebs earns $2 more
ETC earns $32 more for a total of $36
After the disappointing return from the GlycoBank…
Curly’s less than brilliant plan…
Earned only original $2 and sore muscles from lactic acid buildup.
Louie’s Gym
Larry’s least brilliant plan…
Moe’s Bar
Earned only original $2 and alcohol and CO2 poisoning.
Stooges Investments: Review
GlycoBank2, $50 bills$2 interest
Mrs. Krebs $2ETC $32
Net gain $36
Louie’s Gym$0
Net gain $2
Moe’s Bar$0
Net gain $2
The End of the Story
Curly won a “Mr. Universe” contest last year.
Larry had to go to “detox” for a while but now he heads up AA meetings and is doing well.
With all his money, Moe became a wealthy playboy and married well!
And you thought they became famous movie actors!
Hey! How does all this hooha relate to biology for crying
out loud!
Yeah, some of it is real personal
stuff like the chick Moe married!
LOL
It’s respiration you fools! Ya know, to make
energy?
Cellular Respiration: Look familiar?
Glycolysis
Aerobic Respirationw/ Oxygen
Anaerobic Lactic Acid
Fermentationw/out Oxygen
AnaerobicAlcohol
Fermentationw/out Oxygen
Pathway depends on: and oxygen enzymes
The THREE types of ENERGY CONVERSTION are:
1.Aerobic Cellular Respiration
2.Anaerobic Lactic Acid Fermentation
3.Anaerobic Alcohol Fermentation
36 ATP ,Needs Oxygen!
2 ATP, Does NOT need Oxygen!
2 ATP, Does NOT need Oxygen!
Aerobic Respiration
1. Glycolysis: The splitting of glucose.
- occurs in the cytoplasm
C6H12O6 + 2 ATP 2 pyruvic acid + 4 ATP (total net gain of 2 ATP)
2. Kreb’s Cycle and ETC (Electron Transport Chain):
- occurs in the mitochondria
pyruvic acid + oxygen carbon dioxide + water + 34 ATP
For a Grand Total of:36 ATP
Anaerobic Lactic Acid Fermentation
1. Glycolysis: The splitting of glucose.
- occurs in the cytoplasm
C6H12O6 + 2 ATP 2 pyruvic acid + 4 ATP (total net gain of 2 ATP)
2. Lactic Acid Fermentation:
- occurs in the cytoplasm
2 pyruvic acid 2 lactic acid
For a Grand Total of:2 ATP
Anaerobic Alcohol Fermentation
1. Glycolysis: The splitting of glucose.
- occurs in the cytoplasmC6H12O6 + 2 ATP 2 pyruvic acid + 4 ATP (total net gain of 2
ATP)
2. Alcohol Fermentation:- occurs in cytoplasmpyruvic acid alcohol + carbon
dioxide
Anaerobic Lactic Acid Anaerobic Lactic Acid Fermentation:Fermentation:
Pyruvic Acid Lactic AcidEnzymes
Step 1: Glycolysis
Step 2: Anaerobic Lactic Acid Fermentation
Anaerobic Lactic Acid Fermentation Cool Facts!
2 pyruvic acid 2 lactic acid – Lactic Acid Fermentation by Microorganisms
plays an Essential role in the manufacture of Food Products such as YOGURT and CHEESE
– Lactic Acid Production in humans results in muscle fatigue.
Anaerobic Alcohol Anaerobic Alcohol Fermentation:Fermentation:
Pyruvic Acid Alcohol + CO2
Enzymes
Step 1: Glycolysis
Step 2: Anaerobic Alcohol Fermentation
AnaerobicAlcohol Fermentation Cool Facts!
2 pyruvic acid 2 Alcohol + 2CO2
– Alcohol Fermentation by yeast plays an essential role in the manufacture of bread, beer and wine.
Anaerobic Alcohol Fermentation Cool Facts
continuedAlcoholic Fermentation is used to
make wine, beer, and the ethanol added to gasoline to make gasohol.
The fact that alcohol is used to power a car indicated the amount of Energy that remains in the Alcohol Molecules.
So…eat your Wheaties and make lots of ATP!
