The correct order of the stages of aerobic respiration is
- A. Krebs cycle, glycolysis, link reaction, electron transport chain
- B. electron transport chain, glycolysis, Krebs cycle, link reaction
- C. link reaction, glycolysis, Krebs cycle, electron transport chain
- D. glycolysis, link reaction, Krebs cycle, electron transport chain
Explanation
Glucose is first split in the cytoplasm, pyruvate is then decarboxylated to acetyl CoA, the acetyl group is oxidised in the Krebs cycle, and the reduced coenzymes feed the electron transport chain. Any other order runs products before the reactions that make them.
