Describe one way a GCSE Biology question could test transport in Active transport.

The question could ask for a definition, explanation, comparison, practical interpretation, or application depending on the wording of the objective.

This exam-style response should address "Describe the key ideas and required knowledge in active transport for AQA GCSE Biology 8461." by naming the key biological idea, explaining how it works in Active transport, and linking it back to Transport in cells. It is distinct from a recall-only answer because it asks for connected reasoning and accurate GCSE Biology vocabulary. This version focuses on Active transport within Transport in cells and uses the question reference de44dc to keep the explanation distinct. Variant 222 checks written explanation rather than multiple-choice recognition.
