A mineral needed to make haemoglobin, the oxygen-carrying protein in red blood cells.
Used by AQA
Specification 3.2.2.2 · Paper 1
Revise: Dietary MineralsIron is needed to make haemoglobin, the protein in red blood cells that carries oxygen from the lungs to body tissues. Cells need oxygen for aerobic respiration, which releases energy from food.
Link a mineral to a specific function: iron is needed for haemoglobin, whereas calcium and phosphorus help build bones and teeth.
Give named food sources, such as milk for calcium or lentils for iron, rather than writing only ‘healthy foods’.
