When CO ₂ concentration in blood increases breathing becomes:

Options

  1. Ashallower and slow
  2. Bthere is no effect on breathing
  3. Cslow and deep
  4. Dfaster and deeper.

Correct answer

D. faster and deeper.

Step-by-step solution

When CO ₂ concentration in blood increases breathing becomes faster and deeper. The effect of increased CO ₂ is to decrease the affinity of haemoglobin for O ₂ . Thus, due to Bohr's effect the CO ₂ released in respiring tissue accelerates the delivery of oxygen by faster and deeper breathing. Related Theory Bohr and Haldane's effect are two properties of haemoglobin. They help the dissociation of respiratory gases from the haemoglobin molecule based on the physiological conditions of their final destination. Bohr e
