Respiration quiz

15 Questions

Quiz Description

Our main focus in this quiz will be on breathing which is a biological process that all humans alive, animals and plants portray. We take in air all the time and release air all the time. Energy gotten through respiration is used for Growth, metabolism, development as well as maintenance. Here you will find a lot of fascinating topics on Biology such as this. And After you take this quiz, you will learn some new terms, like inspiration, expiration, inhalation, exhalation, bronchi, bronchus and so many other interesting words.

Respiration in its simplest term is the taking in of Oxygen and sending out of Carbon Dioxide. Or  It can simply be defined as breathing. Respiration in man occurs when a man takes in air(inhales), and sends out air(exhales). When this happens, a series of metabolic activities occur in our body system from our mouth to the lungs which is the main organ of respiration.

Respiration from plants and animals helps to balance the CO2:O2 concentration in the atmosphere, and also helps us to keep living as these metabolic activities are needed for one to be alive.

Do you want to know how good you are in Biology, respiration in particular? There are hundreds of quizzes on our website, do well to check them out after this. Take the quiz and find out.

The gases from (i) air breathed in, (ii) air breathed out, (iii) just above a lit bunsen burner flame and (iv) the gases left over after burning a candle inside an up-turned beaker where analysed. From the results quoted below, which analysis is most likely to be from the bunsen flame?


Correct
  • 1:
    74% nitrogen, 1% oxygen, 11% carbon dioxide, 14% water vapour
  • 2:
     75% nitrogen, 10% oxygen, 8% carbon dioxide, 7% water vapour

     78% nitrogen, 21% oxygen, 0.04% carbon dioxide, 1% water vapour
  • 4:
     76% nitrogen, 15% oxygen, 4% carbon dioxide, 5% water vapour
3:

Which statement is FALSE concerning diet and respiration?


Correct
  • 1:
     the more physically active you are, the more quickly your energy reserves are reduced
  • 2:
     chemical energy stored in fibre cannot be used because the fibre cannot be digested
  • 3:
    starch provides energy slower than glucose because starch has to be stored before it is absorbed into the blood stream
  • 4:
     glucose provides energy quicker than starch because glucose can be directly absorbed into the blood stream
4:

Which statement is FALSE when comparing respiration and burning a fuel?


Correct
  • 1:
    respiration is fast and not controlled, burning is rapid and controlled
  • 2:
     both respiration and burning produce waste water and carbon dioxide
  • 3:
      both respiration and burning release heat energy, but only burning gives out light too
  • 4:
     both respiration and burning use up oxygen
5:

Which statement is FALSE about respiration?


Correct
  • 1:
     gases easily pass across the wall of the alveolus because it mainly consists of water
  • 2:
     a face mask filters out dust particles that can irritate or damage the lungs
  • 3:
      dust particles can damage the lung by irritating and covering the inner alveoli surface
  • 4:
     gas exchange in the lungs is very efficient because of the large surface area of the alveoli
6:

Which statement is FALSE concerning diet and respiration?


Correct
  • 1:
     starch provides energy slower than glucose because starch has to be digested before it is absorbed into the blood stream
  • 2:
     chemical energy stored in fibre cannot be used because the fibre cannot be digested
  • 3:
      glucose provides energy much quicker than starch because glucose has a much higher energy content
  • 4:
     the more physically active you are, the more quickly your energy reserves are reduced
7:

Which statement is FALSE about respiration?


Correct
  • 1:
     emphysema victims have difficulty breathing because the damaged alveoli have less surface area
  • 2:
      gases easily pass across the wall of the alveolus because it is thin
  • 3:
     a face mask filters out dust particles that can irritate or damage the lungs
  • 4:
     gas exchange in the lungs is very efficient because of the small surface area of the alveoli
8:
