Question

When CO2 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

Tardigrade Admin · Accepted Answer

When CO2 concentration in blood increases, breathing becomes faster and deeper. The effect of rising CO2 concentration is due to decrease in affinity of Hb for O2. Thus, the CO2 released in the tissues accelerates the delivery of O2 (called Bohr effect), due to which breathing becomes faster and deeper.
