Which type of respiration releases more energy per gram of glucose?

• Aerobic

• Anaerobic

• They both release the same amount

What is the chemical formula for glucose?

• C₆H₁₂O₆

• C₁₂H₆O₁₂

• C₆O₁₂H₆

• 6CH₂O

Where is lactic acid principally broken down in the human body?

• Muscles

• Liver

• Kidneys

• Blood

What is the equation for aerobic respiration?

• C₆H₁₂O₆ + 6O₂ --> 6CO₂ + 6H₂O

• C₆H₁₂O₆ + O₂ --> CO₂ + H₂O

• C₆H₁₂O₆ + 6O₂ --> CO₂ + 6H₂O

• 6C₆H₁₂O₆ + 6O₂ --> 6CO₂ + 6H₂O

Where in the body does respiration take place? Select the best answer.

• The lungs

• The muscles

• All cells

• The blood

What is the purpose of respiration? Select the best answer.

• To release the chemical energy stored in glucose

• To generate heat

• To produce energy

• To absorb oxygen by diffusion

This is an experiment to measure the rate of respiration in seeds. Why is there cotton wool in the mouth of the vacuum flask?

• To allow oxygen into the flask

• To prevent a build up of pressure

• So that the seeds can be watered

• So that the seeds have something to grow roots into
