Anaerobic respiration produces less ATP than aerobic respiration because, after glycolysis (which yields 2 net ATP), pyruvate is not further broken down through the Krebs cycle and electron transport chain. These latter processes require oxygen as the final electron acceptor and generate the majority of ATP.
La respirazione anaerobica produce meno ATP rispetto a quella aerobica perché, dopo la glicolisi (che produce 2 ATP netti), il piruvato non viene ulteriormente scomposto attraverso il ciclo di Krebs e la catena di trasporto degli elettroni, processi che richiedono ossigeno come accettore finale di elettroni e generano la maggior parte dell'ATP.
| Front | Explain why the incomplete breakdown of glucose in anaerobic respiration produces less ATP than aerobic respiration. |
|---|---|
| Back | in anaerobic respiration glycolysis / conversion of glucose into pyruvate , occurs ; produces 2 molecules of ATP (net) ; (only) substrate level phosphorylation (occurs) ; oxygen not available as final electron acceptor |
