complete
place the three stages of aerobic cellular respiration in the correct order from 1 to 3.
electron transport chain
glycolysis
citric acid cycle
done

Explanation:

• Glycolysis: It is the first stage of aerobic cellular respiration. In this process, glucose is broken down into pyruvate.
• Citric acid cycle: Also known as the Krebs cycle, it is the second stage. Pyruvate from glycolysis is further metabolized here.
• Electron transport chain: This is the final stage where a large amount of ATP (adenosine triphosphate, the energy currency of the cell) is produced through oxidative phosphorylation.

Answer:

1. Glycolysis
2. Citric acid cycle
3. Electron transport chain
