1. CELLULAR RESPIRATION

2. TERMINOLOGY Aerobes – require oxygen to make energy
Most plants, animals & some bacteria
Staphylococcus
Anaerobes – not require oxygen to make energy
Some fungi & bacteria (for some O2 can be toxic )
Tetanus
Facultative Anaerobes – function w/ or w/o O2
Yeast
Listeria

3. RESPIRATION vs. Fermentation
C6H12O6 + O > CO2 + H2O C6H12O > CO2 + C2H6O C6H12O > C3H6O3

4. GLYCOLYSIS Anaerobic – no O2 Occurs in cytoplasm
All cells use this process
Prokaryotic
Eukaryotic
Products:
NADH
ATP
Pyruvate

5. Conversion of Pyruvate  Acetyl CoA
Aerobic – O2 needed
Bonds w/ C form CO2
Occurs in mitochondria
Repeated 2x (each molecule glucose makes 2 pyruvates)
Products:
NADH
CO2
Acetyl CoA

6. KREBS CYCLE Aerobic – O2 needed Occurs in mitochondria Cycle spins 2x
Bonds w/ C form CO2
Occurs in mitochondria
Cycle spins 2x
Products:
CO2
NADH
FADH2
ATP

7. ELECTRON TRANSPORT CHAIN
Aerobic – O2 needed
Binds w/ H2 to form water
Occurs in cristae (inner mito. Folds)
Convert all energy molecules into ATP
NADH (gly) x 2 = ___
NADH (kc) x 3 = ___
FADH x 2 = ___

8. TOTAL ENERGY PRODUCTION
ATP - _____ ATP - ______ ATP - _____
Cellular Respiration = ______ ATP

9. FERMENTATION Method energy production when no O2 present
Allows continual cycling glycolysis to occur & limited amount ATP to be produced
Alcoholic Fermentation
Occurs in yeast & bacteria
By-products - CO2 & alcohol
Commercial uses
Baking
brewing
Lactic Acid Fermentation
Occurs large muscles, fungi & bacteria
By-products – lactate
Pain, burning assoc w/ strenuous exercise
Commercial uses
Yogurt
Cheese
