What is the amount of $O_{2}$ supplied to tissues through every $100 \ ml$ of oxygenated blood under normal physiological conditions (in $ml$)?

In mammals,how much $CO_2$ is transported as bicarbonates of sodium and potassium in the blood?

Given below are two statements.
Statement $I$: Carbonic anhydrase enzyme is found in $RBCs$ and is absent in plasma.
Statement $II$: The rate of formation of carbonic acid is very high inside $RBCs$ than in plasma.
In light of the above statements, select the correct answer from the options given below.

Each haemoglobin molecule can carry a maximum of

Refer to the following statements:
$I$. Carbonic anhydrase is present in the erythrocytes.
$II$. In erythrocytes,the carbon dioxide combines with water and is transported.

Every $100 \ ml$ of oxygenated blood can deliver around $............$ of $O_2$ to the tissues under normal physiological conditions. (in $ml$)
