Question: Refer the given figure and answer the question.
Which of the following statement is correct regarding the above figure?
Options:
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 $ HbO_2 $ as similar to Hb at different $ PO_2 $ .
D) None of the above
Show Answer
Answer:
Correct Answer: A
Solution:
[a] The given graph shows the oxygen - haemoglobin dissociation curve.
The relationship between the $ pO_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 $ pO_2 $ .
