$CO_2$ is transported in blood primarily as:

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

Haemoglobin is a red-colored,iron-containing pigment present in $RBCs$. $O_2$ binds with it in a reversible manner to form..........

What is the effect of $CO_2$ concentration on the dissociation of oxyhemoglobin called?

Out of total oxygen transported,the plasma carries . . . . . . in dissolved state.

How many molecules of $O_2$ can one molecule of hemoglobin carry?
