Explanation:

Step1: Recall Cellular Respiration Equation

The chemical equation for cellular respiration is \( \ce{C6H12O6 + 6O2
ightarrow 6CO2 + 6H2O + ATP} \) (energy). So we match the blanks:

1. First reactant is glucose: \( \ce{C6H12O6} \)
2. Second reactant is oxygen: \( \ce{O2} \) (coefficient 6, but in the blank structure, likely just \( \ce{O2} \) as part of the equation)
3. First product (gas) is carbon dioxide: \( \ce{CO2} \) (coefficient 6)
4. Second product is water: \( \ce{H2O} \) (coefficient 6)
5. Energy in the form of ATP.

Step2: Analyze Respiration Types

• 6. First step of cellular respiration is glycolysis, which is anaerobic (doesn't need oxygen).
• 7. Glycolysis takes place in the cytoplasm and breaks down glucose.
• 8. Glycolysis produces pyruvate, \( \ce{NADH} \), and 2 ATP molecules.
• 9. If no oxygen, anaerobic respiration (fermentation) occurs.
• 10. Two types of fermentation: alcoholic and lactic acid, occur in cytoplasm.
• 11. Alcoholic fermentation: yeast, bacteria, etc.
• 12. Alcoholic fermentation produces ethanol (alcohol) and \( \ce{CO2} \) (used in bread, beverages).
• 13. Lactic acid fermentation: muscle cells, some bacteria.
• 14. Lactic acid fermentation produces lactic acid (causes muscle soreness).
• 15. Both processes (aerobic and anaerobic) produce ATP.
• 16. If oxygen present, aerobic respiration occurs.
• 17. Aerobic respiration after glycolysis: Krebs cycle (takes place in mitochondria matrix) and electron transport chain (mitochondria inner membrane).
• 18. After glycolysis, Krebs cycle produces \( \ce{CO2} \), electron carriers, and 2 ATP.
• 19. Then electron transport chain: electrons from carriers, oxygen (final electron acceptor) and hydrogen form water, about 32 - 34 ATP and \( \ce{H2O} \) as waste.

Answer:

1. \( \boldsymbol{\ce{C6H12O6}} \)
2. \( \boldsymbol{\ce{O2}} \)
3. \( \boldsymbol{\ce{CO2}} \)
4. \( \boldsymbol{\ce{H2O}} \)
5. \( \boldsymbol{\ce{ATP}} \)
6. glycolysis, anaerobic
7. cytoplasm, glucose
8. 2
9. anaerobic
10. fermentation
11. yeast (alcoholic fermentation organisms)
12. ethanol (or alcohol)
13. lactic acid (fermentation type)
14. lactic acid
15. ATP
16. aerobic
17. mitochondria (Krebs cycle and ETC location)
18. Krebs, \( \boldsymbol{\ce{CO2}} \)
19. electron transport chain, \( \boldsymbol{\ce{H2O}} \), 32 - 34 (ATP), \( \boldsymbol{\ce{H2O}} \) (waste)
