Q

What is the role of the iron ion?

A
  1. Found in the haem group of haemoglobin for transportation of oxygen around the body
  2. Haemoglobin is a large protein made up of 4 different peptides and iron in the centre
  3. Iron ion binds to the oxygen in the haemoglobin
  4. Fe2+ temporarily becomes Fe3+ when oxygen is bonded until released
