2.4 Inorganic Ions
- Inorganic ions have an electric charge
- Inorganic ions is one which doesn't contain carbon
(although there are a few exceptions)
- Found in organisms where they occur in
solution in the cytoplasm of cells and in
body fluids and as well as part of larger
molecules
- Ferrous Fe2+ ions (Iron ions) are found in
haemoglobin where they play a role in the
transport of oxygen
- Phosphate ions form a structural role
in DNA molecules and a role in
storing energy in ATP molecules
- Hydrogen ions are important in determining
the pH of solutions and therefore the
functioning of enzymes
- sodium ions are important in the transport of glucose and
amino acids across plasma membranes
