What would happen if 
of deoxygenated blood of a person is 48 mm of Hg . In this condition.
Person experience decp breathing and slow breathing rate.
Person experience no change in breathing pattern
His 
dissociation curve remains shifts towards left
dissociation curve remains shifted towards right

(d) Normal partial pressure of carbon dioxide of deoxygenated blood is 45 mmHg . A decrease in 
shifts the curve to the left, while an increase in 
shifts the curve to the right. Thus, when 
of deoxygenated blood of a person becomes 48 mm Hg , his 
dissociation curve remains shifted towards right. The increase in 
reduces the affinity of oxygen to haemoglobin in two ways:
(i) Accumulation of 
causes formation of carbamino compounds, which bind to oxygen and form carbaminohaemoglobin.
(ii) Accumulation of 
causes an increase in 
ion concentration and a decrease in the pH , which will shift the curve to the right.
