Glycolysis Review
Respiration & Glycolysis
• Aerobic Respiration
– Glycolysis creates
Pyruvate, NADH
– Kreb’s (Citric Acid) Cycle
continues
• Anaerobic
Respiration
– Glycolysis creates
Pyruvate, NADH
– NAD molecules recycled
back and forth
– ATP continually
produced by glycolysis
Lactic Acid Fermentation
• Glycolysis creates
– two pyruvates (3C)
– 4ATP (net gain of 2ATP)
– NADH
• L.A.F. Step 1: NADH breaks down pyruvates into lactic acid
– Lactic acid causes muscle burn
– Acids breaks down upon oxygen returning
• L.A.F Step 2: NAD returns to glycolysis
Alcoholic Fermentation
• Glycolysis creates
– two pyruvates (3C)
– 4 ATP (net gain of 2 ATP)
– NADH
• A.F. Step 1: NADH breaks down pyruvates into
ethanol and CO2
• A. F. Step 2: NAD returns to glycolysis
