1. Aerobic vs Anaerobic Respiration
Lactic Acid & Alcohol Fermentation

2. Aerobic Respiration Requires oxygen to create ATP energy
Main way that food is converted into usable energy
Takes place in the mitochondria
Very efficient
1 glucose molecule produces ATP molecules

3. Anaerobic Respiration
Doesn’t require oxygen to produce ATP
Another way food is converted into energy
Takes place in the cytoplasm
Prokaryotes
Cheese, yogurt, sour cream, and pickles
Animals use this process when muscle cells are overworked over a short period of time. (Exercising)
Fermentation
Organisms living in low-oxygenated environments
No mitochondria

4. Lactic Acid Fermentation
Animals and bacteria
For short bursts of energy, exercising
Converts glucose into 2ATP + Lactic Acid

5. Alcohol Fermentation Yeast and other microorganisms
Converts glucose into alcohol + CO2 + 2ATP
Causes bread to rise
Produces alcoholic beverages
Both types of fermentation only produce 2ATP molecules for every 1 molecule of glucose.
