Glycolysis Review
Glycolysis and Respiration• Glycolysis
– Creates: ATP, Pyruvate, NADH
– Leads to either:
1) Aerobic Respiration With oxygen
present Kreb’s (Citric Acid)
Cycle Electron transport
chain
2) Anaerobic Respiration Without oxygen Fermentation
O2
No O2

Lactic Acid Fermentation
• Glycolysis
– Glucose (6C) broken down into two pyruvates (3C)
– 4ATP + NADH created
• L.A.F. Step 1: Happens when muscles do not receive oxygen
– NADH breaks down pyruvates into lactic acid (causes burn)
– Lactic acid breaks down upon oxygen returning
• L.A.F Step 2: NAD returns to glycolysis
• Glycolysis can break down another glucose to create 4 ATP
During heavy exercise, the oxygen you inhale mainly goes to your brain. Your muscles are now lacking oxygen.
But your muscles need ATP if you want to continue your exercise.
There must be a way to make ATP without the help of oxygen.

Alcoholic Fermentation
• Glycolysis– Glucose (6C) broken down into two pyruvates (3C)– 4ATP + NADH created
• A.F. Step 1: Happens in yeasts & some plants– NADH breaks down pyruvates into ethanol and CO2
• A. F. Step 2: NAD returns to glycolysis• Glycolysis can break down another glucose to create 4 ATP
CO2 from yeast causes bread to rise. So why is bread nonalcoholic?
Public Service Announcement: Proper Use of Alcohol
Maple Center Counseling Program
• The Safe Ride Program is a confidential service to Beverly Hills students. If a teenager feels he/she cannot drive safely, he/she can call (888) 654-3211 for a free ride home. This service is available every Friday and Saturday night from 10:00pm to 2:00am and on Prom Night and New Year’s Eve from 10:00pm to 6:00am.
Review• What does the word aerobic imply? Anaerobic?• How many ATP molecules are created by either type
of fermentation?• Before fermentation, which process must first take
place?• What is produced during glycolysis?• Which molecule from glycolysis is used to break apart
pyruvate during fermentation?• Besides alcohol, what is a waste product of alcoholic
fermentation?• Where can you find the phone number to the Maple
