Question

what is the role of respiratory pigment in respiration. give one example

Answer 1

Answer.

A respiratory pigment is a molecule which increase the oxygen carrying capacity of the blood.

Example

Haemoglobin in humans and other vertberates.

Answer 2

The role of those pigments is primarily to assist within the transport of molecular gas. Therefore they're distinguished from metabolic process enzymes, that are involved with the metabolic consumption of gas. Four clearly coloured teams of metabolic process pigments exist among invertebrates: hemoglobins (purple, become orange-red with oxygen), chlorocruorins (green, become red with oxygen), hemocyanins (colorless, become blue with oxygen), and hemerythrins (colorless, become red with oxygen).
