Q. Statement I: About 70% of $CO_2$ is carried by haemoglobin as carbaminohaemoglobin.
Statement II: Neural signals from pneumotaxic centre in pons region of brain can increase the duration of inspiration.

Breathing and Exchange of Gases

Solution:

About 20- 25% of $CO_2$ is carried by haemoglobin as carbaminohaemoglobin.
Neural signals from pneumotaxic centre in pons region of brain can reduce the duration of inspiration and hence, alters the respiratory rate.
