Which of the following substances does not inhibit the transport of oxygen in the blood?

If $ppCO_2$ is high and pH is low,then it will result in:
$i$. increase in affinity of haemoglobin for $O_2$
$ii$. decrease in affinity of haemoglobin for $O_2$
$iii$. oxygen dissociation curve shifts to left
$iv$. causes release of $O_2$ for diffusion into tissue cells
$v$. $H^+$ and $HCO_3^-$ ions combine to form carbonic acid

Select the $INCORRECT$ statement regarding the transport of respiratory gases.

Carbon dioxide is transported in the blood to the lungs in the form of:

Body tissues obtain ${O_2}$ from oxyhaemoglobin because of its dissociation caused by:

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