Biology respiration Flashcards
What are the two forms of respiration
Aerobic respiration and anaerobic respiration
Why is anaerobic respiration less effective than aerobic respiration?
Anaerobic respiration releases a small amount of energy.
Why do we start panting?
To remove carbon dioxide and take in oxygen at a higher rate.
Why does muscle cells carry out anerobic respiration?
To meet the increased energy demand.
What is formed during anaerobic respiration?
Lactic acid.
When does muscles cells incur an oxygen debt?
When there is insufficient oxygen to meet the demands of the vigorous muscular contractions
What is oxygen debt?
It is the amount of oxygen required to remove lactic acid.
How can oxyegn debt be removed?
Continuation of fast heart rate and continuation of deeper and faster breathing
When is oygen debt repaid?
Once the lactic acid is removed.
What is respiration?
Refers to cellular respiration, which is the release of energy when cells break down glucose in the presence of oxygen.
What is breathing?
Air moving in and out of the lungs
Which microorganism give off carbon dioxide when they respire anaerobically?
Yeast.
What is gas exchange?
It is the exchange of gases between an organism and the environment.
Why are amphibians and mammals external surfaces thickened?
For protection and to prevent water loss.
What takes place in the alveoli (air sacs) in the lungs?
The absorption of atmospheric oxygen and the removal of carbon dioxide
