1. What substances are produced by cellular respiration? (2 points) 

O2 and H2O 
CO2 and C6H12O6 
O2 and C6H12O6 
CO2 and H2O 

2. Where does the Krebs cycle occur? (2 points) 

Cytoplasm 
Mitochondrion 
Cell membrane 
Nucleus 

3. During the process of cellular respiration, energy stored in glucose molecules is used to form (2 points) 

oxygen molecules 
NAD+ 
ATP 
carbohydrates 

4. In the Krebs cycle, (2 points) 

pyruvate is broken down into CO2 molecules 
glucose is broken down into NADH and CO2 
CO2is converted into pyruvate and O2 
NADH and CO2 are converted into ATP 

5. What stage of cellular respiration is anaerobic? (2 points) 

Glycolysis 
Calvin cycle 
Electron transport chain 
Krebs cycle 

6. What stage of cellular respiration produces the most ATP? (2 points) 

Electron transport chain 
Glycolysis 
Krebs cycle 
Fermentation 

7. During fermentation, the conversion of pyruvate into lactic acid requires (2 points) 

NADH 
carbon dioxide 
ATP 
oxygen gas 

8. Alcoholic fermentation (2 points) 

forms fewer ATP molecules than cellular respiration 
uses oxygen and ATP molecules as reactants 
occurs in the muscle cells of animals and humans 
gives off carbon dioxide and NADH as products 

I have also attached a picture to question 9 and 10. 
Thank you for you help.
