ATP Production in Cellular Respiration
Total ATP Yield from One Glucose Molecule
| Stage | Location | ATP Produced |
|---|---|---|
| Glycolysis | Cytoplasm | 2 ATP (net) |
| Krebs Cycle | Mitochondrial Matrix | 2 ATP |
| Electron Transport | Inner Membrane | 32-34 ATP |
| Total | 36-38 ATP |
Important Points
- Aerobic respiration is 19 times more efficient than anaerobic
- NADH from glycolysis yields 2-3 ATP depending on shuttle system
- Each NADH in mitochondria yields ~3 ATP
- Each FADH2 yields ~2 ATP
Clinical Relevance
Mitochondrial disorders affect ATP production, leading to muscle weakness, neurological problems, and metabolic issues. Understanding these pathways is crucial for diagnosis and treatment.
Key Takeaways
- •One glucose molecule yields 36-38 ATP
- •Most ATP comes from the electron transport chain
- •Oxygen is the final electron acceptor
- •Without oxygen, only 2 ATP from glycolysis
- •Mitochondria are the powerhouses of the cell
Study Questions
- 1.Why does aerobic respiration produce more ATP than fermentation?
- 2.What is the role of oxygen in the electron transport chain?
- 3.How do uncoupling proteins affect ATP production?
- 4.What happens to pyruvate in the absence of oxygen?
