Cellular respiration 1

What are the reactants of cellular respiration?

• glucose & carbon dioxide
• glucose & oxygen
• water & oxygen
• water & carbon dioxide

The purpose of cellular respiration is to 

• make water
• make ATP
• make glucose
• make  oxygen

In which way are photosynthesis and cellular respiration different?

• Cellular respiration stores ATP, while photosynthesis releases ATP.
• Cellular respiration produces oxygen, while photosynthesis uses oxygen.
• Photosynthesis releases energy, while cellular respiration stores energy.
• Photosynthesis uses carbon dioxide, while cellular respiration produces carbon dioxide.

What is the correct equation for cellular respiration?

• 6O₂ + C₆H₁₂O₆ -> 6CO₂ + 6H₂O + Energy
• 6O₂ + C₆H₁₂O₆ + Energy -> 6CO₂ + 6H₂O
• 6CO₂ + 6H₂O -> 6O₂ + C₆H₁₂O₆ + Energy
• 6CO₂ + 6H₂O + Energy -> 6O₂ + C₆H₁₂O₆

If oxygen is not present what process will occur in yeast cells?

• Alcoholic fermentation
• Respiration
• Photosynthesis
• Lactic acid fermentation

During fermentation, yeast produces CO₂ and

• lactic acid
• alcohol
• hydrogen 
• water

Which process produces the most ATP per molecule of glucose?

• lactic acid fermentation
• aerobic respiration
• alcoholic fermentation
• all are about the same

When glycolysis occurs,

• a molecule of glucose is split
• two pyruvate are made
• some ATP is produced
• all of these

Cells produce ATP most efficiently in the presence of

• water
• carbon dioxide
• oxygen
• radiant energy

Which of the following processes creates the most ATP during aerobic cellular respiration?

• glycolysis
• fermentation
• electron transport chain
• Kreb's cycle
