Inorganic ions occur in solution in the cytoplasm and body fluids of organisms, some in high concentrations and others in very low concentrations
Organisms contain charged mineral particles called inorganic ions, dissolved in their fluids. Some ions are present in large amounts, while others exist in tiny traces.
Real World
A patient treated for diabetic ketoacidosis at an NHS hospital receives IV fluids to restore blood potassium and sodium ion concentrations — tiny shifts in these levels disrupt nerve impulse transmission and heart rhythm.
Exam Focus
When asked about roles of specific ions, name the ion, its concentration context, and its precise function — vague answers about 'mineral ions' score poorly.
Evaluation Scaffold
A four-step framework for high-quality evaluation. Use this for 'assess', 'evaluate', and 'to what extent' questions.
