A) Remain unaffected
B) Slow and shallower
C) Deep breathing and rapidly
D) Deep breathing and normally
Correct Answer: C
Solution :
When concentration of \[C{{O}_{2}}\] increases in blood, the breathing rate increase rapidly and will be deep. The effect of increased \[C{{O}_{2}}\] is to decrease the affinity of hemoglobin for \[{{O}_{2}}\] Thus, due to Bohr's effect the \[C{{O}_{2}}\] released in respiring tissue accelerates the delivery of oxygen by faster and deeper breathing.
