  • question_answer During oxygen transport, the oxyhaemoglobin at the tissue level liberates oxygen to the cells due to

    A)  \[{{O}_{2}}\] concentration is high and \[C{{O}_{2}}\] is low

    B)  \[{{O}_{2}}\] concentration is low and \[C{{O}_{2}}\] is high

    C)  \[{{O}_{2}}\] tension is low and \[C{{O}_{2}}\] tension is high

    D)  \[{{O}_{2}}\] tension is high and \[C{{O}_{2}}\] tension is low

    Correct Answer: C

    Solution :

    Due to low oxygen tension and high carbon dioxide tension, oxyhaemoglobin at the tissue level liberates the oxygen to the cells. This oxyhaemoglobin   after   reaching   tissue. dissociates into oxygen and haemoglobin because the amount of oxygen in tissue is low.Oxygen dissociates from the haemoglobin and diffuses into tissue.
