Example
Marathon
Stage 1 of aerobic system
Works in same way as anaerobic glycolysis (lactic acid) but due to presence of O2 the pyruvic acid combines with coenzyme to produce Acetyl Coenzyme A
Stage 1 flow diagram
Glycogen->glucose->pyruvic acid+coenzyme A + energy-> Acetyl coenzyme A
Stage 1 enzymes
GPP PFK
Stage 2
Krebs cycle
Where is stage 2
Mitochondria
Stage 2 formula
Acetyl CoA + oxaloacetic acid-> citric acid
Citric acid used in krebs cycle
Krebs cycle (stage 2)
- CO2 produced and removed
2 hydrogen atoms produced (oxidation) - 2 ATP
4 regenerate oxaloacetic acid
Stage 3 (electron transport chain)
NAD+FAD->hydrogen carriers
->
NADH+FADH->water+hydrogen electrons->34ATP
Electron transport chain
