Assertion: A sigmoid curve is obtained when percentage saturation of haemoglobin with O2 is plotted against the PO2. Reason: Every 100 mL of oxygenated blood can deliver around 5mL of O2 to the tissues under normal physiological conditions.

Q. Assertion : A sigmoid curve is obtained when percentage saturation of haemoglobin with $O_{2}$ is plotted against the $P O_{2}$ .
Reason : Every $100 m L$ of oxygenated blood can deliver around $5 m L$ of $O_{2}$ to the tissues under normal physiological conditions.
