Cellular Respiration and Fermentation

Which of the following pass high-energy electrons to the electron transport chain?

• NADH and FADH2
• ATP and ADP
• citric acid
• acetyl–CoA

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

• glycolysis
• fermentation
• Krebs cycle
• electron transport

The process carried out by yeasts that causes grape juice to become wine is

• lactic acid fermentation
• yeast mitosis
• alcoholic fermentation
• cellular respiration

Which of the following does NOT perform cellular respiration?

• giraffe
• daisy
• mushroom
• all of the above perform cellular respiration

The products of cellular respiration are the

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

Cellular respiration uses 1 molecule of glucose to produce approximately

• 2 ATP molecules
• 4 ATP molecules
• 30 ATP molecules
• 36 ATP molecules

Cellular respiration is called an aerobic process because it requires

• light
• glucose
• oxygen
• exercise

Breathing heavily after running a race is your body’s way of

• stopping the electron transport chain
• repaying an oxygen debt
• making more citric acid
• restarting glycolysis

The electron transport chain uses high-energy electrons from the Krebs cycle to produce

• convert acetyl-CoA to citric acid
• NADH and FADH2 are waste byproducts of the cycle
• glucose move H+ ions across the inner mitochondrial membrane to produce ATP
• convert glucose to pyruvic acid

Photosynthesis is to chloroplasts as cellular respiration is to

• cytoplasm
• nuclei
• chloroplasts
• mitochondria
