​Which of the following pigments has a high affinity for oxygen? ​

Correct option is A

The correct answer is (a) ​Haemoglobin

Explanation: Hemoglobin is a pigment that has a high affinity for oxygen

Information Booster:

• Hemoglobin and myoglobin are pigments that have a high affinity for oxygen:
• Hemoglobin: A respiratory pigment found in red blood cells that carries oxygen from the lungs to the body's tissues. Hemoglobin's high affinity for oxygen allows it to exchange gases at the alveoli.
• Myoglobin: A pigment that stores oxygen in muscles.
• Other pigments that have an affinity for oxygen include cytochromes, which are heme proteins that participate in redox reactions.
• Factors that affect hemoglobin's affinity for oxygen include: pH, Temperature, Carbon dioxide, 2,3-BPG, and Carbon monoxide.​
