Vedclass · Answer

(D) $CO_2$ is transported in the blood in three main forms:$1$. As bicarbonate ions $(HCO_3^-)$,primarily as sodium bicarbonate $(NaHCO_3)$ in the plasma,which accounts for about $70\%$ of $CO_2$ transport.$2$. As carbaminohemoglobin $(Hb-CO_2)$,where $CO_2$ binds to the amino group of hemoglobin,accounting for about $20-25\%$ of transport.$3$. Dissolved in plasma as carbonic acid $(H_2CO_3)$ or dissolved $CO_2$,accounting for about $7\%$ of transport.Since all these forms are involved in the transport of $CO_2$,the correct answer is $D$.

Blood transports $CO_2$ in which of the following forms?
