Biology Question on Exchange Of Gases
Bohr effect is related with
A
reduced carbon level in lymph
B
reduced oxygen level in haemoglobin
C
oxidised phosphorus level in blood
D
reduced carbon dioxide level in blood.
Answer
reduced oxygen level in haemoglobin
Explanation
Solution
Bohr effect is the phenomenon whereby the affinity of the respiratory pigment of the blood for oxygen is reduced, and the level of carbon dioxide is increased. This facilitates gaseous exchange, because more oxygen is released in the tissues where the amount of carbon dioxide is rising due to metabolic activity. At the same time, more oxygen is taken up at the lungs where the amount of carbon dioxide is low.
