Question

Short / long answer type questions.
Throw light on the importance of hemoglobin in respiration.

Answer 1

• Haemoglobin is the carrier of oxygen to all the living cells for cellular respiration.
  
• Oxygen present in haemoglobin is used and carbon dioxide released during cellular respiration combines with haemoglobin. This blood is termed impure or deoxygenated blood.
  
• This impure blood is carried to the lungs. Haemoglobin releases carbon dioxide and combines with oxygen and is converted into oxyhaemoglobin again to be carried to all living cells through blood circulation.
