Hemoglobin refers to a red protein responsible for transporting oxygen in the blood of vertebrates. The part of the hemoglobin molecule that carbon attaches to is the heme molecule.

What does hemoglobin do after it leaves the cells and returns to lungs?

The carbon dioxide is released as the other parts of the hemoglobin molecule pick up more oxygen for a return trip to the cells.


What is it called when hemoglobin is carries carbon dioxide?

When hemoglobin carries carbon dioxide, it forms carbaminohemoglobin. This occurs in the red blood cells as carbon dioxide is transported from the tissues to the lungs to be exhaled.


What small molecules bind to hemoglobin?

Carbon dioxide and BPG bind to amino acids located on hemoglobin. Oxygen molecules bind to the iron molecules located in the heme. Each hemoglobin molecule can carry up to four oxygen molecules, one on each of the four iron molecules. Nitric oxide can also bind to hemoglobin when either oxygen or carbon dioxide are bound to the hemoglobin.


Does CO2 bind at the same site on the hemoglobin molecule as O2 If not where does CO2 bind?

No. Carbon monoxide binds to the same site as oxygen, i.e. the central iron. Carbon dioxide binds to the globin molecule.


What is the pathway of an oxygen molecule from the atmosphere to its combination with a hemoglobin molecule?

Oxygen reaches the hemoglobin in the blood cells by entering the lungs. The key area of the lungs where the transfer of oxygen and carbon dioxide is made is called the alveoli. The Alveoli has very thin cell walls which allow oxygen and carbon dioxide to pass freely in and out of the blood stream.


What is the most important protein in the physiologically transport of carbon dioxide by blood?

The most important protein involved in the transport of carbon dioxide by blood is hemoglobin. Hemoglobin binds to carbon dioxide in red blood cells and helps transport it from tissues to the lungs, where it can be exhaled.


How does molecule of carbon monoxide differ from a molecule of carbon dioxide?

Carbon monoxide is CO and carbon dioxide is CO2.


How many single and double covalent bonds does a carbon atom have in a carbon dioxide molecule?

Two covalent bonds attach both Oxygen atoms to the Carbon atom. You should have figured that out using the Lewis structure.


How does hemoglobin help with carbon dioxide transport?

No... haemoglobin does not transport carbon dioxide...coz it is our waste which we breathe out....we only take oxygen and after combining with haemoglobin it becomes oxyhaemoglobin.....but if we breathe in pollution for long..... it forms carboxyhaemoglobin.... and it's very harmful to us.
