Question

what is formed when CO2 combines with globin of reduced haemoglobin?where does it occur

Answer 1

Answer :

When haemoglobin combines with carbon-dioxide , the carbon-dioxide is dissolved in the haemoglobin.

An unstable compound is formed .

Equation :-

$\mathsf{Hb+CO_2========>HbCO_2}$

Hence : carbamino-haemoglobin is the product formed.

Where does it occur ?

The process occurs in all the tissues and cells in our body.

The carbon-dioxide is absorbed in R.B.Cs and are excreted through exhalation.

Thank you :) !!

Answer 2

       when CO2 combines with haemoglobin it forms the carbamino haemoglobin

haemoglobin can bind to four molecules of carbon di oxide

       thus haemoglobin carries the co2 from all parts of the body and organs to lungs in the form carbaminohaemoglobin

        then in the lungs the blood looses it co2 and the oxygen from air dissolves in blood to form oxyhaemoglobin which is then transported to various organs of the body by the heart
