| Which of the following statement is correct regarding the above figure? |
A) When percentage saturation of haemoglobin is plotted against the partial pressure of oxygen, a sigmoid curve is obtained.
B) Binding of oxygen with haemoglobin is primarily related to partial pressure of carbon monoxide.
C) The given graph illustrates the amount of \[Hb{{O}_{2}}\] as similar to Hb at different\[P{{O}_{2}}\].
D) None of the above
Correct Answer: A
Solution :
[a] The given graph shows the oxygen - haemoglobin dissociation curve. The relationship between the \[p{{O}_{2}}\] and the percent saturation of haemoglobin when represented on a graph is termed as oxygen haemoglobin dissociation curve. It is S-shaped because of the behaviour of the Hb in different\[p{{O}_{2}}\].
