Explain

In AQA GCSE Biology, Explain means give a linked reason, mechanism, or cause-and-effect account rather than naming a fact. For Animal tissues, organs and organ systems, use Explain to support the objective to explain that digestive enzymes convert large insoluble food molecules into small soluble molecules that can be absorbed into the blood. Related approved keywords for this objective include enzymes. This definition is deliberately scoped to The human digestive system, so it preserves this concept without merging it with neighbouring key terms.
