Question
Why do we need a respiratory pigment to perform respiration?
✓

Answer

The role of the respiratory pigment is primarily to aid in the transport of molecular oxygen and thus help in respiration. A respiratory pigment is any molecule that increases the oxygen. In humans and most other vertebrates, the most common respiratory pigment is a protein the red blood cells in our blood can carry to our tissues and organs is called hemoglobin. It helps in transporting oxygen from lungs to various body tissues and also helps in the removal of carbon-dioxide from cells.
