Inorganic Ions

• Inorganic ions are found in the cytoplasm and body fluids of organisms in various concentrations.
• Each ion type has a specific role based on its properties.
• Study topics include: hydrogen ions and pH; iron ions in haemoglobin; sodium ions in co-transporting glucose and amino acids; phosphate ions in DNA and ATP.
• Students may be asked to link ions to other subjects (eg. iron, haemoglobin, blood).
• Recommendation: create a revision table listing each ion, its importance, and curriculum links.
