Which of the following statements is incorrect regarding the given diagram?
A
It is highly useful in studying the effect of factors like 
and 
concentration, on binding of 
with haemoglobin.
and concentration, on binding of with haemoglobin. B
It is a linear curve which represents saturation of haemoglobin with oxygen.
C
It represents oxygen dissociation curve.
D
Percentage saturation of haemoglobin with oxygen is represented by Y-axis.
Text Solution
Verified by ExpertsThe correct answer is:
B
The oxygen dissociation curve is not linear; it has a characteristic sigmoid (S-shaped) curve. This shape is due to the cooperative binding of oxygen to haemoglobin-where the binding of one oxygen molecule increases the affinity for subsequent oxygen molecules. Factors such as 
concentration and temperature can shift the curve, influencing oxygen binding and release.
