Q. When carbon dioxide concentration in blood increases, breathing becomes

A) Shallower and slow
B) There is no effect on breathing
C) Slow and deep
D) Faster and deeper
Explanation

When carbon dioxide concentration in blood increases, breathing becomes faster and deeper. The effect of increased carbon dioxide is to decrease the affinity of haemoglobin for oxygen. Thus, due to Bohr’s effect, the carbon dioxide released in respiring in respiring tissue accelerates the delivery of oxygen by faster and deeper breathing.
