Worksheet: Anaerobic Respiration

In this worksheet, we will practice recalling the reactants and products of anaerobic respiration, and comparing this process to aerobic respiration.

Q1:

What reactant is required for aerobic respiration to take place but is not required for anaerobic respiration?

  • AWater
  • BCarbon dioxide
  • CLactic acid
  • DGlucose
  • EOxygen

Q2:

Complete the following statements using the words “with” or “without.”

Anaerobic means oxygen.

  • Awith
  • Bwithout

Aerobic means oxygen.

  • Awithout
  • Bwith

Q3:

What product of anaerobic respiration in animal cells is not a product of aerobic respiration?

  • AWater
  • BLactic acid
  • CCarbon dioxide
  • DGlucose
  • EOxygen

Q4:

For the following examples, decide whether the cells in the body are likely to be respiring aerobically or anaerobically.

A person is running a marathon distance of 26 miles over 4 hours.

  • AAerobically
  • BAnaerobically

A child sprints 50 meters down a hallway in 8 seconds.

  • AAnaerobically
  • BAerobically

A rabbit in a garden spots a fox and rapidly jumps away.

  • AAerobically
  • BAnaerobically

Q5:

Which of the following is a disadvantage of having lactic acid in the body?

  • AIf it is not broken down, lactic acid can cause pain in the bones.
  • BIf it is not broken down, lactic acid can change the shape of red blood cells.
  • CIf it is not broken down, lactic acid can cause the muscles to become more alkaline.
  • DThere are no disadvantages of having lactic acid in the body.
  • EIf it is not broken down, lactic acid can cause pain in muscles and muscle cramps.

Q6:

When would the ability of cells to respire anaerobically be an advantage to a human?

  • ADuring short bursts of activity when oxygen intake is limited
  • BDuring long periods of moderate activity when oxygen intake is not limited

Q7:

Which of the following is the scientific term given to the process of anaerobic respiration in yeast?

  • ADecomposition
  • BFermentation
  • CContraction
  • DConversion
  • EDeoxygenation

Q8:

Which of the following is the correct word equation for anaerobic respiration in animal cells?

  • AGlucose carbon dioxide
  • BGlucose + oxygen lactic acid
  • CGlucose lactic acid
  • DGlucose + oxygen carbon dioxide + water
  • ELactic acid glucose

Q9:

The diagram shows a basic outline of an animal cell.

Which letter indicates where anaerobic respiration occurs in the cell?

  • AC
  • BB
  • CA
  • DD

Q10:

What key term in anaerobic respiration is described as the heavy breathing that occurs after intense exercise to break down lactic acid?

  • AOxygen debt
  • BCarbon dioxide debt
  • CRespiration debt
  • DLactic acid debt

Q11:

Which of the following statements about respiration in animals is correct?

  • AAerobic respiration transfers less energy than anaerobic respiration.
  • BAnaerobic respiration generates more carbon dioxide than aerobic respiration.
  • CAnaerobic respiration transfers less energy than aerobic respiration.
  • DOver the same period of time, anaerobic and aerobic respiration will transfer the same amount of energy.
  • EAerobic respiration generates more lactic acid than anaerobic respiration.

Q12:

Without including energy/ATP, state the word equation for anaerobic respiration in yeast cells.

  • AGlucose ethanol + carbon dioxide
  • BGlucose carbon dioxide
  • CEthanol glucose + carbon dioxide
  • DGlucose + carbon dioxide ethanol
