 The expression "feel the burn" means that a person exercising is doing.........

• lactate fermentation
• alcoholic fermentation
• kreb's cycle
• aerobic respiration

What do we call this lab set up?

• a barometer
• a respirometer
• a manometer
• a spirometer

What is the purpose of the cotton wool?

• to stop the maggots touching the soda lime
• to keep the oxygen in the space above the maggots
• to insulate the maggots from the cold
• to keep the boiling tube bright

Why is the tube to the right in the boiling tube sealed?

• To allow gases to enter and exit the respirometer
• To stop gases entering and exiting the respirometer
• To keep the maggots warm
• There is no reason to seal that tube

What do you expect to see happen?

• The liquid in the manometer will move UP the ruler
• The liquid in the manometer will move DOWN the ruler
• The liquid in the manometer will NOT move
• The liquid in the manometer will move UP and DOWN the ruler

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

Which are made in BOTH aerobic and anaerobic cell respiration in animals?

• pyruvate and ATP
• pyruvate and lactate
• ATP and carbon dioxide
• lactate and carbon dioxide

Two different species of bacteria are examined. Scientists find that Species X always produces CO₂ & H₂O during cellular respiration. Species Y always produces ethyl alcohol & CO₂. Which conclusion can be made from these observations?

• Only Species Y is aerobic

• Only Species X is aerobic

• Both Species X and Y are aerobic

• Both Species X and Y are anaerobic
