Protein
Haemoglobin is a large…that carries oxygen around the body
Protein
Haemoglobin is made up of 4 polypeptide chains, each with an…. ion in its centre
Iron
What part of Haemoglobin binds to oxygen
Iron ion
(There are 4 iron ions per Haemoglobin as each Haemoglobin is made up of 4 polypeptide chains and each polypeptide chain has an iron ion in its centre)
The…of hydrogen ions in the environment determine PH
Concentration
4 key inorganic ions (ions that don’t contain carbon) that I need to learn are…
Iron ions
Hydrogen ions
Sodium ions
Phosphate ions
The more H+ ions that are present (higher concentration), the… the PH
Lower
(Which makes the environment more acidic)
Hydrogen ions are important because their concentration determines the … of an environment and PH affects enzyme- controlled reactions
PH
True or false, PH affects enzyme controlled reactions
True
(And PH is determined by concentration of hydrogen ions)
Sodium ions help…and…to cross the cell membrane

Properties
Chemical formula of iron ion in Haemoglobin (found in centre of polypeptide chains)
Fe^2+
Fe^2+ vs Fe^3+ when looking at role of iron ions in Haemoglobin
Fe^2+ ions are found in the centre if the polypeptide chains in the Haemoglobin and bind to oxygen
Once bonded to oxygen, Fe^2+ temporarily becomes Fe^3+until oxygen is released
In the Haemoglobin, the …temporarily becomes ….when it binds to oxygen (until the oxygen is released)
Fe^2+
Fe^3+
In the Haemoglobin, the …temporarily becomes ….when it binds to oxygen (until the oxygen is released)
