Lesson Worksheet: Respiration with Oxygen Science

In this worksheet, we will practice describing the chemical reactions of aerobic respiration, their location, and their significance to energy transfer inside organisms.

Q1:

Which gas is required for aerobic respiration?

  • AOxygen
  • BHydrogen
  • CCarbon dioxide
  • DNitrogen

Q2:

Complete the sentence: All organisms need to transfer to allow their cells to keep working and to stay alive.

  • Aelectricity
  • Blight
  • Cenergy

Q3:

Complete the sentence: The carbon-containing molecules in the food you eat are a form of stored energy that is transferred by the rearrangement of molecules during the chemical reaction of respiration.

  • Achemical
  • Bheat
  • Ckinetic
  • Dlight
  • Eelectrical

Q4:

Which statement about diffusion in respiring cells is correct?

  • AOxygen and glucose diffuse across the cell membrane into cells.
  • BOxygen and carbon dioxide diffuse across the cell membrane into cells.
  • CCarbon dioxide diffuses across the cell membrane into cells, and oxygen diffuses out.
  • DCarbon dioxide and glucose diffuse across the cell membrane into cells.
  • ECarbon dioxide and oxygen diffuse across the cell membrane, but glucose does not.

Q5:

From which organ are the two waste products of respiration excreted?

  • ASkin
  • BIntestines
  • CLungs
  • DKidneys

Q6:

What happens to the energy transferred when molecules are rearranged during respiration in order for your muscles to contract?

  • AHeat (thermal) stored
  • BHeat (thermal) kinetic
  • CKinetic heat (thermal)
  • DStored kinetic
  • EStored heat (thermal)

Q7:

Organisms are often classified into groups, as follows:

  • Animals
  • Plants
  • Bacteria
  • Fungi
  • Protists (e.g., Amoeba and Euglena)

Which groups carry out respiration?

  • AAnimals, fungi, some protists, and some bacteria
  • BAnimals, bacteria, fungi, and protists
  • CAnimals, bacteria, and fungi
  • DAnimals, plants, fungi, and protists
  • EAnimals, plants, bacteria, fungi, and all protists

Q8:

What happens to the energy transferred when molecules are rearranged during respiration in order to maintain body temperature?

  • AHeatthermalstored()
  • BHeatthermalkinetic()
  • CStoredkinetic
  • DStoredheatthermal()
  • EKineticheatthermal()

Q9:

The figure shows the organelle where aerobic respiration takes place. What is its name?

  • AVacuole
  • BChloroplast
  • CMitochondrion
  • DNucleus
