A) shallower and slow
B) there is no effect on breathing
C) slow and deep
D) faster and deeper
Correct Answer: D
Solution :
When \[C{{O}_{2}}\]concentration in blood increases, breathing becomes faster and deeper. The effect of increased \[C{{O}_{2}}\]is to decrease the affinity of haemoglobin 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.
