Question

Define oxygen dissociation curve. Can you suggest any reason for its sigmoidal pattern.
Please give a easy answer​

Answer 1

Answer:

The dissociation curve is sigmoidal pattern because of the binding of oxygen to haemoglobin. As the first oxygen molecule binds to haemoglobin, it increases the affinity for the second molecule of oxygen to bind. Subsequently, haemoglobin attracts more oxygen.

Answer 2

Define oxygen dissociation curve.

Ans. The oxygen dissociation curve is a graph with oxygen partial pressure along the horizontal axis and oxygen saturation on the vertical axis, which shows an S-shaped relationship.

Can you suggest any reason for its sigmoildal shape?

Ans. The sigmoid shape of the dissociation curve is because of the binding of oxygen to haemoglobin.
