How are oxygen and carbon dioxide transported in the blood?

Answer 1

By attaching to an iron-based protein in the blood called haemoglobin.

A single haemoglobin molecule can take in 4 oxygen molecules (#O_2#).

That means 8 Oxygen atoms.

When oxygen gets attached, the haemoglobin turns red.

#CO_2# follows the same principle but there a number of other ways it is carried through the blood. The most common way is in the form of bicarbonate ions .

Oxygen is primarily transported in the blood bound to hemoglobin within red blood cells, while a small amount is dissolved directly in the plasma. Carbon dioxide is transported in three forms: dissolved in plasma, as bicarbonate ions, and bound to hemoglobin.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
