Explanation:

Cellular respiration has three main stages: glycolysis, the Krebs cycle (also known as the citric acid cycle), and the electron transport chain. Glycolysis breaks down glucose into pyruvate. In anaerobic conditions (fermentation), pyruvate can be converted into either lactic acid or ethanol and \(CO_2\). In aerobic conditions, pyruvate enters the Krebs cycle. The Krebs cycle produces \(CO_2\), ATP, NADH, and \(FADH_2\). The electron transport chain uses \(O_2\) as the final electron acceptor to produce a large amount of ATP (32 ATP in the diagram) and \(H_2O\) (since \(O_2\) combines with electrons and \(H^+\) ions).

Answer:

1. Glycolysis
2. Pyruvate
3. 2 ATP
4. Lactic acid or Ethanol
5. Krebs cycle (Citric acid cycle)
6. Pyruvate
7. 2 ATP
8. NADH, \(FADH_2\)
9. \(CO_2\)
10. \(H_2O\)
