Question

Why rbc are considered the best transporting of oxygen?

Answer 1

Explanation:

The protein inside (a) red blood cells that carries oxygen to cells and carbon dioxide to the lungs is (b) hemoglobin. ... This is because the hemoglobin molecule changes its shape, or conformation, as oxygen binds. The fourth oxygen is then more difficult to bind. That's why RBC are considered the best transporting of oxygen.

Answer 2

Answer:

Because RBC does not have a nucleus when it matures and also it does not contain any mitochondria, and it is oval biconcave in shape for maximizing surface area. therefore it is highly energy efficient carrier of oxygen.
