IB Biology D3.2.7 Phenylketonuria (PKU)
Practise explaining PKU inheritance, biochemical cause, diet links and treatment evidence from structured questions and data graphs.
How this is tested
- explain PKU as an inherited recessive condition affecting phenylalanine breakdown
- link protein-rich diets to phenylalanine build-up in people with PKU
- evaluate treatment data by weighing changes in blood phenylalanine over time
