What Will Happen If Carbon Monoxide Combines With Haemoglobin
This is why carbon monoxide is a killer.
What will happen if carbon monoxide combines with haemoglobin. We know that heamoglobin combines with oxygen to form oxyheamoglobin. They prevent the formation of oxyhaemoglobin and thus oxidation cannot take place in the cells the person is likely to suffer from breathing problems which can be fatal. In doing so the binding pocket became substantially less comfortable for ce co. It strangles the body s cells for oxygen.
This oxygen diffuses across the walls of the capillaries into tissues. But since carbon monoxide was so good and oxygen so poor to start with. Symptoms are often described as flu like and commonly include headache dizziness weakness vomiting chest pain and confusion large exposures can result in loss of consciousness arrhythmias seizures or death. Oxygen is generally a poor ligand.
Heamoglobin hb has a greater tendancy to combine with co than oxygen. The treatment for carbon monoxide poisoning is to give the. Carboxyhemoglobin or carboxyhaemoglobin symbol cohb or hbco is a stable complex of carbon monoxide and hemoglobin hb that forms in red blood cells upon contact with carbon monoxide co. Co binds tightly and rapidly to haemoglobin and crowds out oxygen.
Carboxy haemoglobin stifles the release of oxygen into the cells from normal haemoglobin. Carbon monoxide is generally a good ligand that can bind to metal centres well. Carbon monoxide replaces oxygen in the bloodstream causing hypoxia an abnormal reduction of oxygen in the body tissues. Carbon monoxide binds to the hemoglobin molecule blocking the oxygen molecule from binding to that cell.
The capillaries of circulatory system deliver the oxygen rich blood to the tissues of the body. Nature did everything to make oxygen a comfortable home in haemoglobin. The classically described cherry red skin rarely occurs. The blood transports this oxygen to various cells of our body.
What will happen if carbon monoxide combines with haemoglobin. This reduces the oxygen carrying capacity of the blood. The deadly effect of carbon monoxide was known as long ago as greek and roman times when the gas was used for executions 1 in 1857 claude bernard postulated that its noxious effect was caused by reversible displacement of oxygen from haemoglobin to form carboxyhaemoglobin 2 in 1926 it became apparent that hypoxia was caused not only by deficient oxygen transport but also by poor tissue uptake. Haemoglobin by combining with carbon monoxide lead to the death of the individual due to suffocation.
Co carbon monoxide is caused due to the incomplete burning of fuels. Carbon monoxide poisoning typically occurs from breathing in carbon monoxide co at excessive levels. Haemoglobin has a higher affinity for carbon monoxide than oxygen and hence co combines with the haemoglobin and reaches all the cells of the body thus harming them.
