1. Fermentation

2. Step 1: Glycolysis Where? In cytoplasm What happens?
Mitochondria
Glucose
C6H12O6 C C
ATP
ATP C C
En-zyme C C
Where? In cytoplasm
What happens?
A) Glucose (from our food) is broken down
B) 2 ATP molecules released for use by the cell

3. Step 2: Fermentation
During prolonged exercise, the oxygen you inhale mainly goes to your brain. Your muscles are now lacking oxygen.
Yeast perform alcoholic fermentation to make bread. Why isn’t bread alcoholic?
How to relieve sore muscles:
Massage
Bananas
Stretch after
Hydrate
Alcohol evaporates in the baking process
Muscle cells perform fermentation to keep you going!
Two Types of Fermentation (both anaerobic):
A) Lactic Acid fermentation
Performed by animals when muscles are not receiving oxygen
Lactic acid waste created
B) Alcoholic fermentation
Performed by yeast, some plants, bacteria
Alcohol waste created

4. What’s after Glycolysis?
Creates: ATP, Glucose fragments
Leads to either:
Aerobic Respiration
With oxygen present
Kreb’s Cycle
Electron transport chain
Anaerobic Respiration
Without oxygen
Fermentation
Allows glycolysis to restart
glycolysis
ATP
fermentation
No O2 O2
ATP

5. Lactic Acid vs. Alcoholic Fermentation
glycolysis
glycolysis
Lactic acid
Alcohol + CO2
Lactic acid fermentation
Alcoholic fermentation
Lactic Acid
Alcoholic
Location: Cytoplasm
Amount of ATP created: Zero
The Point? Make molecules to restart glycolysis
Waste: Lactic acid
Location: Cytoplasm
Amount of ATP created: Zero
The Point? Make molecules to restart glycolysis
Waste: Alcohol and CO2

6. Aerobic Respiration Fermentation
Where? In the mitochondria
Steps? Kreb’s cycle and electron transport chain
What happens? Glucose fragments converted into 34 ATPs
With oxygen present
Glycolysis:
-- In the cytoplasm
-- Glucose is split into fragments
-- 2 ATP created
If oxygen is lacking
Fermentation
Where? In the cytoplasm
What happens?
Glucose fragments are broken into either lactic acid or alcohol
Molecules to restart glycolysis created (No ATP)
Glycolysis restarts

7. Kobe Public Service Announcement: Proper Use of Alcohol

8. 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) for a free ride home.
