Biomolecules - Result Question 38
####38. The reactions of (a) oxygen and (b) carbon monoxide with haeme (the prosthetic group of haemoglobin) give
[1997]
(a) only oxygen-haeme complex
(b) only carbon monoxide-haeme complex
(c) both oxygen-haeme and carbon monoxidehaeme complexes but oxygen-haeme complex is more stable
(d) both oxygen-haeme and carbon monoxidehaeme complexes but carbon monoxidehaeme complex is more stable
Show Answer
Solution:
- (d)
$ \begin{aligned} & Hb+CO \longrightarrow HbCO \text{ (stable compound) } \\ & \text{ carboxy haemoglobin } \end{aligned} $
