Name the respiratory pigment found in erythrocytes.
Answers
Haemoglobin is the pigment which gives erythrocytes their red colour. It binds to oxygen and some carbon dioxide in the transport of these gases through the blood stream. Oxygen in used in cellular respiration and carbon dioxide is released in the process. Haemoglobin is protein in nature, and consists of 4 sub units, (as seen in the picture below).

Answer:
The respiratory pigment found in erthrocytes is Haemoglobin.
⇒ Haemoglobin Both the red badge of courage and the blue blood of the aristocrat are due to haemoglobin, the pigment that gives blood its color.
⇒ Take it away, by removing the blood cells, and the resulting plasma is a very pale yellow.
⇒ Haemoglobin combines with oxygen, enabling blood to carry 70 times more than if the oxygen were simply dissolved.
⇒ Animals that are physically active and larger than a pea could scarcely survive without it.
⇒ Each haemoglobin molecule can combine with four oxygen molecules, but with no more.
⇒ The complete combination is called oxygen saturation.
⇒ The degree of combination depends on the pressure of the gas; in healthy humans the pressure in the alveoli of the lungs is above that needed for saturation.
