Question

All of the following are ways in which carbon dioxide is carried by the blood EXCEPT:

A. bound to oxyhemoglobin.
B. as bicarbonate ion (HCO3-).
C. dissolved in the plasma.
D. bound to an amino acid in hemoglobin, forming carbaminohemoglobin.

Answer 1

Answer:

bound to oxyheamoglobin

Explanation:.

Oxyheamoglobin is formed from the reaction of oxygen with haemoglobin.it is the oxygen loaded form of haemoglobin for delivery of oxygen to needed remote areas of the body.

.Hb        +      4O2       ⇒    HbO8

haemoglobin  oxygen    oxyhaemoglobin

Haemoglobin is a protein molecule that binds with oxygen. It has high affinity for oxygen with its four haem groups. Each haem group has binding iron.(Fe). When it is binds  with oxygen it is bright red, and turns purple when it unloaded oxygen at target point.

It has no association with carbondioixde transports except oxygen transport .

Carbon dioxide, is transported as the  listed three options(b,c,d) in the questions. Therefore  bound to oxyheamoglobin is  wrong, and it is the correct answer
