Chapter 9: Respiration and Fermentation

Cellular respiration is called an aerobic process because it requires

• light
• exercise
• oxygen
• glucose

Which compounds are produced by the two main types of fermentation? 

• NAD+ or ATP
• alcohol or lactic acid
• glucose or carbon dioxide
• ADP or ATP

Which of the following is NOT a stage of cellular respiration?

• fermentation
• electron transport
• glycolysis
• Krebs cycle

Cellular respiration benefits organisms by 

• forming carbon dioxide
• breaking down glucose
• transferring energy to ATP
• consuming oxygen

Photosynthesis is to chloroplasts as cellular respiration is to

• chloroplasts
• cytoplasm
• mitochondria
• nuclei

The products of photosynthesis are the

• products of cellular respiration
• reactants of cellular respiration
• products of glycolysis
• reactanta of fermentation

 In glycolysis, each glucose molecule is broken down into 

• six molecules of carbon dioxide
• four molecules of ATP
• two molecules of pyruvic acid
• two molecules of ATP

Glycolysis provides a cell with a net gain of

• 2 ATP
• 4 ATP
• 18 ATP
• 36 ATP

Cellular respiration uses 1 molecule of glucose to produce approximately______ATP molecules.

• 2
• 4
• 28

• 36

Lactic acid fermentation occurs in

• bread dough
• any environment containing oxygen
• muscle cells
• mitochondria
