  • Question 1
    1 / -0
    Which of the following is/are the site of glycolysis?
    Solution
    Cytoplasm is the site of glycolysis, which is the breakdown of glucose by enzymes, releasing energy and pyruvic acid.
  • Question 2
    1 / -0
    Which of the following processes is complementary to respiration?
    Solution
    Photosynthesis is complementary to respiration.as the products of one reaction are the reactants of another.So, cellular respiration consumes sugars and oxygen and creats carbon dioxide, water, and releases energy. Photosynthesis combines energy, carbon dioxide, and water to form sugar and oxygen.
  • Question 3
    1 / -0
    The number of ATP molecules produced during aerobic and anaerobic respiration are _______ and ______, respectively.
    Solution
    The number of ATP molecules produced during aerobic and anaerobic respiration are 38 and 2, respectively.
  • Question 4
    1 / -0
    Which of the following is not formed during anaerobic respiration?
    Solution
    Acetyl-CoA is not formed during anaerobic respiration. Anaerobic respiration is a form of respiration using electron acceptors other than oxygen.
  • Question 5
    1 / -0
    In what form is the energy released during respiration stored?
    Solution
    Energy released during respiration is stored in the form of ATP.It transports chemical energy within cells for metabolism.
  • Question 6
    1 / -0
    Which of the following is caused by the biological oxidation of respiratory substrate?
    Solution
    Loss of hydrogen is caused by the biological oxidation of respiratory substrate.
  • Question 7
    1 / -0
    Why is aerobic respiration more advantageous than anaerobic respiration?
    Solution
    Aerobic respiration is more advantageous than anaerobic respiration because it produces more energy.
  • Question 8
    1 / -0
    What does RQ indicate?
    Solution
    RQ indicates nature of respiratory substrate.It is the ratio of the volume of carbon dioxide evolved to that of oxygen consumed by an organism, tissue, or cell in a given time.
  • Question 9
    1 / -0
    What should be the RQ in respiration of substrate of organic acids?
    Solution
    Option (4) is the correct answer.
  • Question 10
    1 / -0
    Which of the following has the highest RQ?
    Solution
    Malic acid has the highest RQ and its value is 1.33.
  • Question 11
    1 / -0
    Respiratory roots are found in
    Solution
    Respiratory roots are found in jussiaea.These roots are white and spongy filled with air that keep plants floating.
  • Question 12
    1 / -0
    The sum total of all reactions occurring in the body, whether constructive or destructive is known as
    Solution
    The sum total of all reactions occurring in the body, whether constructive or destructive is known as metabolism.
  • Question 13
    1 / -0
    Which of the following are called breathing roots?
    Solution
    Pneumatophores are called breathing roots. These are the roots found above the ground.
  • Question 14
    1 / -0
    Which of the following can respire in the absence of oxygen?
    Solution
    Yeast can respire in the absence of oxygen and it produces alcohol as a by-product.
  • Question 15
    1 / -0
    How many times does a person respire in one minute?
    Solution
    A person respires around 16 - 20 times in a minute.
  • Question 16
    1 / -0
    Respiration in frog is performed with the help of
    Solution
    The frog has three respiratory surfaces on its body that it uses to exchange gas with the surroundings: the skin, in the lungs and on the lining of the mouth.
  • Question 17
    1 / -0
    In the human body, fats are stored in
    Solution
    In the human body, fats are stored in adipose tissue. Its main role is to store energy in the form of lipids, although it also cushions and insulates the body.
  • Question 18
    1 / -0
    In reptiles, respiration takes place through
    Solution
    In reptiles, respiration takes place through skin. It is known as cutaneous respiration.
  • Question 19
    1 / -0
    What happens to diaphragm at the time of inspiration?
    Solution
    During inspiration (breathing in), the diaphragm contracts, drawning downward, creating a vacuum in the thoracic cavity. This vacuum inflates the lungs by drawing air into the body through the trachea, or windpipe.
  • Question 20
    1 / -0
    Exchange of gases in lung alveoli occurs through
    Solution
    Exchange of gases in lung alveoli occurs through simple diffusion,O2 diffusing from the alveoli into the blood & CO2 from the blood into the alveoli.
