Question

how does carbon monoxide affect red blood cells (rbcs)?
multiple choice
the hemoglobin within the rbc bind to carbon monoxide.
the carbon monoxide converts to carbon dioxide.
the hemoglobin rejects carbon monoxide.
the rbcs clump together.
it causes them to shrivel.

Explanation:

Carbon - monoxide has a high affinity for hemoglobin in red - blood cells. It binds to hemoglobin much more strongly than oxygen, forming carboxy - hemoglobin. This prevents the normal binding of oxygen to hemoglobin and reduces the oxygen - carrying capacity of red - blood cells.

Answer:

The hemoglobin within the RBC bind to carbon monoxide.
