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?
- A
- B
- C
- D
- E
Q9:
The figure shows the organelle where aerobic respiration takes place. What is its name?
- AVacuole
- BChloroplast
- CMitochondrion
- DNucleus
Q10:
The figure shows the structure of skeletal muscle tissue.
Why do muscle cells have lots of mitochondria?
- AThey need to transfer a lot of energy to produce heat.
- BThey need to transfer a lot of energy for movement.
- CThey need to transfer a lot of energy to make new cells.
- DThey need to transfer a lot of energy to make proteins.
- EThey need to transfer a lot of energy to absorb oxygen.
