Answer:
What happens immediately after hemoglobin binds to carbon dioxide in the body's cells is that carbon dioxide is carried through the blood vessels back to the lungs.
Explanation:
Carbon dioxide (COâ‚‚) is a waste product that comes from cell metabolism, and is potentially harmful, so it must be eliminated. The hemoglobin molecule that reaches the tissues loaded with oxygen (Oâ‚‚) releases it, increasing its affinity for COâ‚‚, which binds to it.
Once COâ‚‚ is attached to the hemoglobin in the red blood cells, it travels through the blood vessels, the veins, to reach the right side of the heart and pass to the lungs, where it will be released with expiration.
The other options are not correct because:
- COâ‚‚ must be transported by the blood before it is exhaled through the lungs.
- COâ‚‚ is not exchanged for Oâ‚‚ in the hemoglobin, the hemoglobin must release Oâ‚‚ before it can bind to the COâ‚‚.
- COâ‚‚ does not diffuse into the plasma, but must bind to the hemoglobin molecule to be transported.
