Fermentation
• Anaerobic: Creates ATP without oxygen
• Two Types
• 1) Lactic Acid fermentation
– Performed by animals
• 2) Alcoholic fermentation
– Performed by yeast, some plants, bacteria
Lactic Acid Fermentation
• Only performed when muscles are lacking oxygen during heavy use
Lactic Acid Fermentation
• Only performed when muscles are lacking oxygen during heavy use• During Glycolysis
– Glucose broken into fragments to release 2ATP

Lactic Acid Fermentation
• Only performed when muscles are lacking oxygen during heavy use• During Glycolysis
– Glucose broken into fragments to release 2ATP• During Lactic Acid fermentation
– No ATP made– Lactic acid waste created (causes sore muscles)– Molecules to restart glycolysis created
• The point? Allows muscles to restart glycolysis

Lactic Acid Fermentation
How to relieve sore muscles:1)Massage2)Bananas3)Stretch after4)Hydrate
• Only performed when muscles are lacking oxygen during heavy use• During Glycolysis
– Glucose broken into fragments to release 2ATP• During Lactic Acid fermentation
– No ATP made– Lactic acid waste created (causes sore muscles)– Molecules to restart glycolysis created
• The point? Allows muscles to restart glycolysis
Glycolysis:-- In the cytoplasm-- Glucose is split into fragments-- 2 ATP created
Lactic Acid fermentation
Where? In the cytoplasm
What happens?Glucose fragments are broken into lactic acidMolecules to restart glycolysis createdNo ATP created
Aerobic Respiration
Where? In the mitochondria
Steps? Kreb’s cycle and electron transport chain
What happens? Glucose fragments converted into 34 ATPs
With oxygen present
If oxygen is lacking
Glycolysis restarts
Alcoholic Fermentation
• Performed by microorganisms (yeast)
• During Glycolysis– Glucose broken into fragments to release 2ATP
• During Alcoholic fermentation– No ATP made– Alcohol and CO2 waste created– Molecules to restart glycolysis created
• The point? Allows yeast to restart glycolysis
Kobe Public Service Announcement: Proper Use of Alcohol
The Maple Center Counseling
• Safe Rides are available on Friday and Saturday nights from 10:00 pm to 2:00 am for teens living in Beverly Hills. High school students can call for a free ride home when they are under the influence of drugs and/or alcohol. When the teenager calls the Safe Ride number, the TMCC counselor assigned to the 24-hour HELP-LINE arranges for that teen to be picked up by the Beverly Hills Cab Company and taken home. Services are confidential.
• (888) 654-3211 for a free ride home.
