Worksheet: Aerobic Respiration

In this worksheet, we will practice recalling the reactants and products of aerobic respiration, and explaining the importance of respiration for organisms.

Q1:

  • BCarbon dioxide
  • CSulfur dioxide
  • DOxygen

Q3:

Not including energy/ATP, state the correct word equation for aerobic respiration.

  • AOxygen + water carbon dioxide + glucose
  • BOxygen + glucose carbon dioxide + water
  • COxygen + carbon dioxide glucose + water
  • DWater + glucose carbon dioxide + oxygen

Q4:

  • AThe large intestine
  • BThe lungs
  • CThe heart
  • DThe stomach
  • EThe small intestine

Q5:

What subcellular organelle is the main site of aerobic respiration?

  • ACytoplasm
  • BNucleus
  • CCell membrane
  • DMitochondria
  • ERibosomes

Q6:

During the process of aerobic respiration, energy is released from the breakdown of glucose.

This energy is stored in the form of a molecule in the cell. What is the name given to this molecule?

  • AATP
  • BTPA
  • CACP
  • DAPP

Q7:

Which of the following is not a use of ATP in animals?

  • ARegulation of body temperature
  • BSimple diffusion of substances across cell membranes
  • CActive transport of substances across cell membranes
  • DMovement and locomotion
  • ESynthesis of large molecules from smaller ones

Q8:

Aerobic respiration requires oxygen. How is this oxygen delivered to cells for respiration?

  • ABy the nervous system
  • BBy white blood cells
  • CBy red blood cells
  • DBy active transport
  • EBy chemical messengers

Q9:

The diagram provided shows the basic structure of a root hair cell.

How can root hair cells use the energy transferred during aerobic respiration in a plant?

  • ARoot hair cells use energy to actively transport mineral ions from soil to root.
  • BRoot hair cells use energy to actively transport water from soil to root.
  • CRoot hair cells use energy to move water by osmosis from soil to root.
  • DRoot hair cells use energy to diffuse mineral ions from soil to root.

Q10:

For the following statement, state whether the rate of cellular respiration increases, decreases, or stays the same.

As the intensity of exercise increases, the rate of cellular respiration .

  • Astays the same
  • Bdecreases
  • Cincreases

Q11:

While excluding energy/ATP, state the correct and balanced chemical (symbol) equation for aerobic respiration.

  • A6CO+6O6HO+CHO2226126
  • BCHO+6CO6O+6HO6126222
  • CCHO+6HO6CO+6O6126222
  • DCHO+6O6CO+6HO6126222

Q12:

Which of the following is correct about cell activity and the number of mitochondria?

  • AThe more active the cell, the lower the number of mitochondria.
  • BThere is no correlation between the activity of a cell and the number of mitochondria it contains.
  • CThe more active the cell, the higher the number of mitochondria.

Q13:

What is the main organ responsible for absorbing the glucose required for aerobic respiration from the diet?

  • AThe stomach
  • BThe large intestine
  • CThe small intestine
  • DThe heart
  • EThe lungs

Q14:

As glucose breaks down in aerobic respiration, it transfers energy to the surroundings.

What type of chemical reaction is this?

  • AExothermic
  • BEndothermic

Q15:
