Human nutrition — IGCSE Biology (0610) questions by topic
Human nutrition questions calculate nutrient amounts per serving from a yoghurt table, identify the rectum on a labelled digestive system diagram, complete a table linking digestive structures to their functions and letters, and state the meaning of chemical digestion.
Identify, state, describe, explain and complete span 1 to 24 marks across 95 real questions from 2023 to 2025 papers. Because nutrient calculations depend on reading the correct row from a data table before any working begins, submitting a calculated answer for instant marking catches a misread serving size or nutrient value the moment it happens.
