Respiration
Biology · 50 practice questions
Respiratory organs and surfaces; mechanism of gaseous exchange in plants and animals; aerobic and anaerobic respiration.
- Explain the significance of respiration and describe glycolysis and the Krebs cycle in outline with reference to ATP production.
- Describe respiratory organs and surfaces (body surface, gill, trachea, lungs, stomata, lenticel) and the mechanism of stomatal opening/closing.
- Examine the role of oxygen in energy release and the effects of insufficient oxygen supply.

Try a few questions
- Practice question 1
ATP, produced during respiration, specifically functions as the
- A.main structural component of the cell membrane
- B.main genetic material used to pass on inherited characteristics
- C.a factor entirely unrelated to providing energy for cellular activities
- D.main energy currency used to power cellular activities
Show the answer
D. main energy currency used to power cellular activities
ATP, produced during respiration, specifically functions as the main energy currency used to power cellular activities.
- Practice question 2
The operculum, found in bony fish, specifically functions mainly to
- A.cover and protect the gills
- B.produce the mucus that coats the external surface of the fish's own scales
- C.a factor entirely unrelated to covering and protecting the gills
- D.store excess oxygen absorbed from the surrounding water
Show the answer
A. cover and protect the gills
The operculum, found in bony fish, specifically functions mainly to cover and protect the gills.
- Practice question 3
Yeast, a facultative anaerobe, specifically is capable of carrying out
- A.only aerobic respiration, with no capacity for any anaerobic process at all
- B.both aerobic and anaerobic respiration depending on oxygen availability
- C.only anaerobic respiration, with no capacity for any aerobic process at all
- D.a factor entirely unrelated to carrying out either form of respiration
Show the answer
B. both aerobic and anaerobic respiration depending on oxygen availability
Yeast, a facultative anaerobe, specifically is capable of carrying out both aerobic and anaerobic respiration.
