  • Question 1
    1 / -0
    A person travelling from sea level to high altitudes can develop 
    Solution
    As we travel from sea level to high altitudes,  the concentration of oxygen in the atmosphere decreases, which results in hypoxia. Hypoxia is a condition of oxygen shortage in the tissue. It causes mountain or altitude sickness characterized by breathlessness, headache, nausea, vomiting etc.
  • Question 2
    1 / -0
    This apparators is used to show that

    Solution
    A small animal like cock roach is used in the experiment. Two conical hasler A and B are taken. In one flask live cockroach is placed and in the other a dead one. It was observed that to flames of candle goes out faster in the flask containing the living animal showing that some oxygen has been used by it during respiration.
  • Question 3
    1 / -0
    Respiration may occur in the absence of oxygen in
    Solution
    Respiration can be carried out in the presence of oxygen (aerobic) or in the absence of oxygen (anaerobic). Fermentation is a special type of anaerobic respiration carried out by microorganisms. Common yeast is a microorganism which can carry out alcoholic fermentation where they respire in absence of oxygen produces alcohol, carbon dioxide and less amount of energy. Therefore, the correct answer is option C.
  • Question 4
    1 / -0
    The breakdown of Pyruvate to give Carbon dioxide, water and energy takes place in the ___.
    Solution
    Correct Answer- B
    Explanation- 
    • The breakdown of pyruvate in order to generate carbon dioxide, water, and energy (ATP) in the presence of oxygen is known as aerobic respiration.
    • Aerobic respiration mainly occurs in the eukaryotic cells when they have oxygen in sufficient amount and it takes place in the Mitochondria.
    • Hence, the correct answer is Mitochondria.
  • Question 5
    1 / -0
    _________ is the volume of air inhaled in a single breath. 
    Solution
    The total lung capacity of the adult male is six liters. Tidal volume is the volume of air inhaled in a single, normal breath. Inspiratory capacity is the amount of air taken in during a deep breath, while residual volume is the amount of air left in the lungs after forceful respiration.
    Therefore, the correct answer is option B.
  • Question 6
    1 / -0
    In blood, CO2_2 in transported majorly as
    Solution
    CO2_2 enters RBC after its diffusion into the blood at the tissues. A small amount is become attached to haemoglobin and forms carbaminohemoglobin. A major amount of the CO2_2 combines with water and forms carbonic acid. The carbonic acid dissociates into hydrogen ions and bicarbonate ions, which are then diffused out of red blood cells into the plasma. Thus, the majority of carbon dioxide is carried in form of bicarbonate ions. 
    So, the correct answer is option B.
  • Question 7
    1 / -0
    α\alpha -1 antitrypsin is used to treat
    Solution
    α\alpha -1 antitrypsin is an enzyme that serves to defend body from infection via regulating functioning of other enzymes. Its deficiency causes many disorders including emphysema. Emphysema is characterized by progressive destruction of alveolar surface thereby reducing the surface area for gaseous exchange and is regulated by regular supply of antitrypsin.
    Therefore, the correct answer is option A.
  • Question 8
    1 / -0
    Dead space air in man is
    Solution
    Dead space is the volume of air, which is inhaled that does not take part in the gas exchange, either because it remains in the conducting airways, or reaches alveoli that are not perfused or poorly perfused. It averages about a third of the resting tidal volume (450-500 mL), which is approx. 150 mL. Hence, option B is correct.
  • Question 9
    1 / -0
    Amount of CO2\displaystyle { CO }_{ 2 } in expired air is about
    Solution
    Amount of CO2CO_2 in expired air is 4 - 5%. Hence, answer should be C.
    Compositon of exhaled air is 78.04% nitrogen, 13.6% - 16% oxygen, 4% - 5.3% carbon dioxide, 1% argon and other gases.
  • Question 10
    1 / -0
    If a large number of people are enclosed in a room, then
    Solution
    If a large number of people are enclosed in a room, then oxygen will be used for their respiration and carbon dioxide will be produced and released in to the room. So, the amount of oxygen will be decreased and the carbon dioxide will be increased.
