Haemoglobin is a globular protein. A single haemoglobin protein contains 4 heme pigments which contain positively-charged iron (Fe2+) which is what binds reversibly with oxygen (O2-). When the O2 reaches the tissue cells where it needed, the Fe2+ releases the O2.

Is needed to transport oxygen in red blood cells?

It is either nucleus, haemoglobin, thick outer cell wall or microvilli.


A molecule of hemoglobin can hold how many molecules of oxygen in the blood transport?

Four heme groups, so I think four molecules of oxygen can be transported by one molecule of haemoglobin.


Why is haemoglobin red?

haemoglobin is red because is carrys oxygen around our body when blood is in contact with oxygen it turns red same


How does carbon monoxide behave as a toxic gas?

Carbon monoxide is produced by incomplete combustion of hydrocarbons. Haemoglobin in your blood is not a stable compound, such that it can transport oxygen around your body. What carbon monoxide does is to react with the haemoglobin to form carboxyhaemoglobin, which is a stable compound, and you wouldn't get enough oxygen, which then you die of asphyxiation (if I didn't forget anything).


Can carbon monoxide damage the heart?

Haemoglobin ensures the oxygen carrying property of red blood cells. Usually, four oxygen molecules can reversibly bind with one haemoglobin molecule in red blood cells. Oxygen is thus transported around the body in the circulatory system.Hb + 4O2 ⇌ Hb(O2)4Note: Hb is haemoglobin; Hb(O2)4 is oxyhaemoglobinCarbon monoxide binds very tightly to haemoglobin in red blood cells to form carboxyhaemoglobin, thereby preventing haemoglobin from binding with oxygen to transport oxygen. Therefore carbon monoxide is toxic and can kill people. It does not really "damage the heart" so to speak, but it does prevent the circulatory system from performing its function.Carbon dioxide binds to the red blood cells better than oxygen does, and your body does not get enough oxygen and you suffocate to death.Carbon monoxide is a toxic gas. In high concentrations can be lethal.

Why white cells do not have haemoglobin?

Leucocytes don't contain haemoglobin because function of haemoglobin is to transport Oxygen and WBCs don't have to transport Oxygen.

haemoglobin


What is the role of haemoglobin in red blood cells?

it transports oxygen (there are 4 atoms of iron in one haemoglobin, which means that it can transport 4 molecules of oxygen..)


Red blood cells transport which 2 chemicals in the body?

Red blood cells have haemoglobin which helps in the transport of oxygen and carbon dioxide.


Which mineral is found in haemoglobin?

Iron is the mineral found in hemoglobin. It is essential for the transport of oxygen in the blood.


What makes red blood cells red and able to transport oxygen?

It is the haemoglobin in the cells which allow them to carry oxygen and its also the reason they are red as haemoglobin is red.


Describe oxygen transport in the red blood cell?

Red blood cells contain a substance called haemoglobin. Oxygen dissolves in haemoglobin to form oxyhaemoglobin. This compound travels in the blood and is taken to all the cells


The oxygen carrying substance in a red blood cell?

POtatos <==That is not correct, idiots!


Do white blood cells contain haemoglobin?

No, haemoglobin is only found in red blood cells. It is a substance that is required to take up oxygen for transport from the lungs to the rest of our body.


What protein combines with oxygen in the blood for transport?

The protein haemoglobin found in red blood cells binds reversibly with oxygen. It is the oxygen transporter in blood, and when combined with oxygen the product is oxyhaemoglobin. One haemoglobin molecule binds with four oxygen molecules in accordance with the chemical equation: Hb + 4O2 -> Hb(O2)4 Note: Hb is haemoglobin; Hb(O2)4 is oxyhaemoglobin


Is needed to transport oxygen in red blood cells?

Why squids blood contains haemocyanin?

Since squids do not have haemoglobin they use haemocyanin to bind and transport oxygen throughout their body.
