When temperature decreases,the oxyhaemoglobin dissociation curve will become:

The ratio of oxyhaemoglobin and haemoglobin in the blood is based upon:

Binding of $O_{2}$ with haemoglobin is primarily dependent upon:
$I.$ Partial pressure of $O_{2}$
$II.$ Partial pressure of $CO_{2}$
$III.$ Hydrogen ion concentration
$IV.$ Temperature
Choose the correct option.

What are $P$ and $Q$ in the given reaction?
$CO _2+ H _2 O \underset{Q}{\stackrel{P}{\rightleftharpoons}} H _2 CO _3 \underset{Q}{\stackrel{P}{\rightleftharpoons}} HCO _3^{-}+ H ^{+}$

How much $CO_2$ is added to every $100\,ml$ of blood by the tissues (in $,ml$)?

Which of the following factors is favourable for the formation of oxyhaemoglobin in the alveoli of human lungs?
